Advantages of the Pirkle-Type<br />
Chiral Stationary Phases<br />
Universal Solvent Capability<br />
The entire family of Regis’ Pirkle-Type Chiral Stationary Phases (CSP’s)<br />
can be used in BOTH normal and reversed-phase solvents. Due to the<br />
fact that all of the Pirkle-Type CSP’s are covalently bonded, the columns<br />
can tolerate all commonly used mobile phase combinations.<br />
Column Durability<br />
Another advantage of covalent bonding is column durability. Listed<br />
below are a few distinct benefits associated with the Pirkle-Type CSP’s:<br />
• Long lasting columns<br />
• Bonded selector will not leach off the silica gel<br />
• Can tolerate sample overload<br />
• Can utilize strong solvents for cleaning<br />
• Columns are fully reversible<br />
• Compatible in SFC and SMB applications<br />
Ability to Invert Elution Order<br />
All of the Pirkle-Type CSP’s, with the exception of Naphthylleucine, are<br />
available in both enantiomeric forms. This allows the Chromatographer<br />
to invert the elution order of the enantiomers by simply switching<br />
columns. This advantage is essential when determining enantiomeric<br />
purity when the trace enantiomer should elute before the major. Elution<br />
order is also important in preparative chromatography because when<br />
the desired enantiomer elutes first, purity and production efficiency<br />
increases.<br />
Chromatographic Efficiency<br />
Unlike most Chiral columns on the market, Pirkle-Type Chiral HPLC<br />
columns show excellent chromatographic efficiency. The high density of<br />
binding sites allows larger amounts of sample to be injected without<br />
major changes in column performance.<br />
Ease of Scale-up<br />
Pirkle-Type CSP’s were designed to allow the Chromatographer to scaleup<br />
their separation from analytical to preparative in a linear fashion.<br />
Regis uses the highest grade silica gels available on the market today.<br />
The 5-micron CSP’s are bonded on Exsil ® . Our 10-micron and 16micron<br />
CSP’s are bonded on Kromasil ® . Synthesis of the chiral selectors,<br />
bonding of the different CSP’s, and column production is all performed<br />
by Regis in one facility. This allows Regis total control over the product<br />
line. This also allows Regis to perform special requests for the customer,<br />
including custom bonding and custom column packing.<br />

Pirkle Chiral Stationary Phases<br />
The Pirkle-Concept Chiral Stationary Phases generally fall into three classes: π-electron<br />
acceptor/π-electron donors, the π-electron acceptors and the π-electron donors. With<br />
Pirkle Phases, chiral recognition occurs at binding sites. Major binding sites are classified<br />
as π-basic or π-acidic aromatic rings, acidic sites, basic sites, and steric interaction sites.<br />
Aromatic rings are potential sites for π-π interactions. Acidic sites supply hydrogens for<br />
potential intermolecular hydrogen bonds-the hydrogen is often an amido proton (N-H)<br />
from an amide, carbamate, urea, or amine. Basic sites, such as π-electrons, sulfinyl or<br />
phosphinyl oxygens, and hydroxy or ether oxygens, may also be involved in hydrogen<br />
bond formation. Steric interactions may also occur between large groups.<br />
π-Electron Acceptor/π-Electron Donor Phases<br />
• WHELK-O 1<br />
• WHELK-O 2<br />
• ULMO<br />
• DACH-DNB<br />
The latest and most revolutionary addition to the Pirkle-Concept series is the π-electron<br />
acceptor/π-electron donor phase. This concept is an innovative incorporation of both<br />
π-acceptor and π-donor characteristics, resulting in a phase that can be used for a wide<br />
variety of compound groups.<br />
WHELK-O 1<br />
The Whelk-O 1 Chiral Stationary Phase is based on 1-(3,5-Dinitrobenzamido)-1,2,3,4,tetrahydrophenanthrene.<br />
This phase allows separation of underivatized racemates from a<br />
number of families including amides, epoxides, esters, ureas, carbamates, ethers,<br />
aziridines, phosphonates, aldehydes, ketones, carboxylic acids, and alcohols.<br />
The Whelk-O 1 was originally designed for the separation of underivatized non-steroidal<br />
anti-inflammatory drugs (NSAIDs). This π-electron acceptor/π-electron donor phase<br />
exhibits an extraordinary degree of generality, allowing resolution of a wide variety of<br />
underivatized racemates. This broad versatility observed on the Whelk-O 1 column,<br />
compares favorably with polysaccharide-derived chiral stationary phases. In addition,<br />
because of the Whelk-O 1’s covalent nature, this chiral phase is compatible with all<br />
commonly used mobile phases, including aqueous systems – a distinct advantage over<br />
polysaccharide-derived chiral stationary phases. Other advantages include column<br />
durability, excellent efficiency, elution order inversion allowing availability of both<br />
enantiomeric forms, and excellent preparative capacity.<br />
WHELK-O 2<br />
The Whelk-O 2 is the covalent trifunctional version of the Whelk-O 1. The Whelk-O 2<br />
retains the same chiral selector but modifies the support to silica from a monofunctional<br />
linkage to a trifunctional. In most cases, the enantioselectivity remains the same allowing<br />
the separation of the analogous family of racemates as does the Whelk-O 1.<br />

Whelk-O 2 was designed to enhance the stability of the stationary phase due to<br />
hydrolysis while using strong organic modifiers such as trifluoroacetic acid. The Whelk-<br />
O 2 is ideal for preparative separations since the material is bonded on 10 µm 100 Å<br />
spherical Kromasil silica. This allows the preparative chromatographer to perform method<br />
development on their analytical column and immediately scale-up to larger diameter<br />
columns.<br />
ULMO<br />
The ULMO chiral stationary phase was developed by Austrian Researchers, Uray, Lindner,<br />
and Maier. This CSP has a general ability to separate the enantiomers of many racemate<br />
classes, and is particularly good at separating the enantiomers of aryl carbinols.<br />
The ULMO CSP is based on a 3,5-Dinitrobenzoyl derivative of diphenylethylene-diamine.<br />
DACH-DNB<br />
The innovative DACH-DNB CSP was designed by Italian chemists Dr. Francesco<br />
Gasparrini, Misiti and Villani at Rome University “La Sapienza.” The DACH-DNB CSP;<br />
which contains the 3,5-dinitrobenzoyl derivative of 1,2-diaminocyclohexane, has been<br />
found to resolve a broad range of racemate classes including amides, alcohols, esters,<br />
ketones, acids, sulfoxides, phosphine oxides, selenoxides, phosphonates,<br />
thiophosphineoxides, phosphineselenides, phosphine-boranes, β-lactams, organometallics,<br />
atropisomers and heterocycles.<br />
π-Electron Acceptor Phases<br />
Introduction to Regis Chiral Stationary Phases REGIS<br />
• Pirkle 1-J<br />
• α-Burke 2<br />
• β-Gem 1<br />
• Leucine<br />
• Phenylglycine<br />
The π-electron acceptor Pirkle Chiral Stationary Phases can be used to separate a wide<br />
range of enantiomers without derivatization, as demonstrated for the following classes of<br />
solutes: secondary benzyl alcohols, mandelic acid analogs, α-hydroxy-α-aryl<br />
phosphates, α-tetralol analogs, propranolol analogs, β-hydroxy-aryl sulfoxides, alkylaryl<br />
sulfoxides, diaryl sulfoxides, aryl-substituted cyclic phthalides, aryl-substituted<br />
lactams, aryl-substituted succinimides, aryl-substituted hydantoins, bi-β-naphthol and its<br />
analogs, and α-aryl acetamides.<br />
PIRKLE 1-J<br />
The Pirkle 1-J CSP is based on 3-(3,5-Dinitrobenzamido)-4-pheny-β-lactam. This unusual<br />
β-lactam structure significantly alters its molecular recognition properties. The Pirkle 1J is<br />
useful for the direct separation of underivatized β-blocker enantiomers. It can also be<br />
used for the separation of the enantiomers of arylpropionic acid NSAID’s as well as other<br />
drugs.<br />
α-Burke 2<br />
The α-Burke 2 phase, first prepared by J. A. Burke III, a graduate student of Dr. Pirkle, is<br />
derived from dimethyl N-3,5-dinitro-benzoyl-α-amino-2,2-dimethyl-4-pentenyl<br />
phosphonate. The α-Burke 2 has been specifically designed to directly separate the<br />
enantiomers of β-blockers without chemical derivatization, but this chiral phase is not<br />
limited solely to the separation of β-blocker enantiomers. It also resolves the enantiomers<br />
of many compounds separated on π-acceptor Pirkle type chiral stationary phases.<br />
β-GEM 1<br />
β-Gem 1 is a π-acceptor chiral stationary phase and is derived from N-3,5dinitrobenzoyl-3-amino-3-phenyl-2-(1,1-dimethylethyl)-propanoate.<br />
For a great many analytes, this chiral phase considerably outperforms its widely used<br />
analog, phenylglycine. It can separate anilide derivatives of a wide variety of chiral<br />
carboxylic acids, including nonsteroidal anti-inflammatory agents.<br />

Phenylglycine<br />
Naphthylleucine<br />
ChiroSil<br />
Leucine<br />
LEUCINE<br />
The leucine CSP is based on the 3,5-dinitrobenzoyl derivative of leucine. This π-acceptor<br />
phase demonstrates enhanced enantioselectivities for several classes of compounds,<br />
including benzodiazapines.<br />
PHENYLGLYCINE<br />
Phenylglycine is based on the 3,5-dinitrobenzoyl derivative of phenylglycine.<br />
This CSP resolves a wide variety of compounds which contain π-basic groups. These include:<br />
aryl-substituted cyclic sulfoxides, bi-β-naphthol and its analogs, α-indanol and α-tetralol<br />
analogs, and aryl-substituted hydantoins.<br />
π-Electron Donor Phases<br />
• NAPHTHYLLEUCINE<br />
The naphthylleucine phase is based on the N-(1-naphthyl) derivative of leucine. These<br />
columns resolve essentially the same class of compounds as does the naphthylalanine<br />
column, but typically with enhanced enantioselectivities for amino acids.<br />
This π-donor chiral phase resolves DNB derivatives of amino acids as the free acid when using<br />
the reversed-phase mode. In the classic normal-phase, this CSP can resolve the amides and<br />
esters of DNB amino acids and will display typical alphas between 10 and 40.<br />
Davankov Ligand Exchange Chiral Stationary Phase<br />
• DAVANKOV<br />
The Davankov chiral stationary phase is useful for the separation of underivatized amino<br />
acid enantiomers. This phase operates according to the principles of ligand-exchange<br />
chromatography (LEC), a technique pioneered by professor V. Davankov.<br />
The Davankov column typically requires a mobile phase of aqueous methanol containing<br />
copper (II) acetate. Regis provides either an HPLC column, or a kit which allows the user to<br />
convert a standard ODS column into a Davankov Chiral Stationary Phase.<br />
Protein-Based Chiral Stationary Phases<br />
Regis Technologies carries a line of protein-based chiral columns manufactured by<br />
ChromTech AB, Sweden. For additional product information and a Protein-Based Chiral<br />
Stationary Phase application guide, please contact Regis directly.<br />

RStech Corporation ChiroSil ® RCA(+) and SCA(-)<br />
18 Crown-Ether Chiral Stationary Phases<br />
• ChiroSil RCA(+)<br />
• ChiroSil SCA (-)<br />
Developed by RStech Corporation in Daejeon, Korea, the ChiroSil phase is the newsest<br />
addition to our chiral line of columns. This phase is prepared by a covalent trifunctional<br />
bonding of (+) or (-)-(18-Crown-6)-tetracarboxylic acid as the chiral selector.<br />
This phase which is available in analytical as well as preparative columns, is an excellent<br />
choice for the separation of amino acids and compounds containing primary amines.<br />
Like our other line of columns, this phase is highly durable, has universal solvent<br />
compatibility, and has the ability to invert elution order.<br />
As described above, Regis’ Chiral columns can be used to separate a wide variety of<br />
enantiomers in numerous compound groups. Please refer to the Product List on page 7 for<br />
particular column types, sizes, configurations and product numbers. Consult the application<br />
separation data section that begins on page 8 for information regarding specific chiral<br />
separations on a wide variety of compounds. See Application Indexes on page 85 for<br />
particular compounds or column types of interest.<br />

Frequently Asked Questions<br />
ABOUT PIRKLE-TYPE CHIRAL STATIONARY PHASES AND COLUMNS FROM REGIS<br />
Throughout the past 20 years, the Sales and Technical persons at<br />
Regis have fielded hundreds of different questions related to our<br />
Chiral Stationary Phases (CSP’s). Listed here you will find some of<br />
the frequently asked questions. By no means is this a complete list,<br />
if you have questions regarding chiral chromatography, please feel<br />
free to contact Regis directly or pass your question on through one<br />
of our distributors.<br />
What is the pressure rating of your columns?<br />
All analytical (25cm x 4.6 mm i.d.) and semi-preparative<br />
(25cm x 10.0 mm i.d.) columns manufactured by Regis can<br />
tolerate pressures up to 6000 psi. Larger columns will tolerate<br />
3000 psi. It is very important not to exceed the maximum pressure<br />
rating for any HPLC column as you may disrupt the integrity of the<br />
silica bed and destroy the column.<br />
Can Regis columns be reversed?<br />
Yes, all columns packed by Regis are fully reversible. In fact, Regis<br />
was the first column manufacturer to sell a fully reversible HPLC<br />
column. It is recommended to reverse your column frequently. This<br />
helps keep the frit surface from becoming clogged with undissolved<br />
sample or particulates in the mobile phase, thus extending the<br />
column life.<br />
What is the pH range of your columns?<br />
All of Regis’ Chiral phases are bonded on silica. The recommended<br />
pH range is 2.5 to 7.5. Limited usage outside of this pH range can<br />
be tolerated, but it has been proven that extended usage outside of<br />
the range will decrease column life.<br />
Can your columns be used in normal and reversed-phase<br />
solvents?<br />
Yes, all Pirkle-Type Chiral HPLC columns can be used in BOTH<br />
normal and reversed-phase solvents. Generally, the Pirkle-Type<br />
CSP’s will give better separations by using them with normal-phase<br />
solvents. There are numerous examples, however; where<br />
separations with reversed-phase solvents will outperform those with<br />
normal-phase solvents.<br />
Can I use the same column for reversed-phase and normalphase<br />
solvent systems while doing method development?<br />
Yes, just make sure you completely flush out the column with a<br />
miscible solvent such as IPA or ethanol. We recommend at least<br />
20 column volumes.<br />
How long does it take your columns to equilibrate?<br />
The column should equilibrate after about 20 column volumes.<br />
When you are switching from normal to reversed-phase solvent<br />
systems and vise-versa, flush the column with a miscible solvent for<br />
20 column volumes. It should take another 20 column volumes to<br />
equilibrate. The equilibration volumes may vary depending on the<br />
composition of the mobile phase.<br />
What type of silica do you use?<br />
Regis exclusively uses Exsil ® for our 5-micron material and<br />
Kromasil‚ for 10 and 16-micron material. Both brands of silica are<br />
100 angstrom in pore size.<br />
Do you always need a modifier in the mobile phase?<br />
No modifiers are usually needed for initial method development.<br />
Modifiers can be used to improve peak shape and resolution when<br />
the samples are extremely basic or acidic in nature. Acetic acid or<br />
ammonium acetate are recommended for acidic compounds, and<br />
triethylamine, diethylamine or ammonium acetate are<br />
recommended for basic compounds. Usually 0.1% of modifier is all<br />
that is required. Note: Although TFA may be used as a modifier,<br />
its use should be limited. Acetic acid usually works as well as TFA.<br />
Can I use your columns for SMB chromatography and SFC?<br />
Yes, many analytical and preparative chromatographers use<br />
Pirkle-Type Chiral columns in both SFC and SMB. Special<br />
hardware is necessary for certain column dimensions.<br />
What is the difference between Whelk-O 1 and Whelk-O 2?<br />
Although the Whelk-O 1 and Whelk-O 2 both share the same<br />
Chiral selector, they have distinct differences. The Whelk-O 1 is<br />
monofunctionally bonded to silica and the Whelk-O 2 is<br />
trifunctionally bonded. The Whelk-O 2 was designed to tolerate<br />
strong acidic modifiers such as TFA. The Whelk-O 2 was designed<br />
for preparative use and is not available on 5-micron silica. Due to<br />
the fact the Whelk-O 2 is a trifunctional bond, coverage on the silica<br />
will be less than with Whelk-O 1. This decrease in the actual number<br />
of bonded sites will decrease selectivity and not allow for exact<br />
reproducibility of a method developed on a Whelk-O 1 column.<br />
Does my compound need an aromatic ring to achieve<br />
separation on a Pirkle-Type Chiral column?<br />
In most cases (not all), yes. Chiral recognition occurs at binding<br />
sites. The potential π-π interaction that can occur between the<br />
aromatic rings on the Chiral selector and the aromatic ring on the<br />
sample is a major factor in achieving selectivity. Binding does<br />
occur at other sites such as acidic sites, basic sites and steric<br />
interaction sites—this is why you do not always need a ring—but<br />
by far, the π-π interaction is the major binding site.<br />
Can I use the Pirkle-Type Chiral columns in polar organic mode?<br />
Yes, even though the success rate is very poor, you can use the<br />
columns in Polar Organic mode. We do not recommend dedicating<br />
a slot in your method development station for a Pirkle-Type Chiral<br />
column if you are exclusively running in Polar Organic mode. Add<br />
another Pirkle-Type column to your normal-phase<br />
system to achieve a higher success rate.<br />
What sampling loading can I expect from Pirkle-Type Chiral<br />
HPLC columns?<br />
The typical loading range – with relative retention’s (alpha) greater<br />
than 1.3—is ~4-16 mg of sample per gram of packing. Below are<br />
typical loadings for some of the different column sizes: Note:<br />
Factors, such as solubility, will greatly affect loading capacity.<br />
Analytical column, 25cm x 4.6mm, ~ 3.5 grams of packing,<br />
loading is 14-56 mg/ injection.<br />
Semi-prep column, 25cm x 10.0mm, ~ 16 grams of packing,<br />
loading is 64-256 mg/ injection.<br />
Prep column, 25cm x 21.1mm, ~ 72.5 grams of packing,<br />
loading is 288-1,152 mg/ injection.<br />

STEP 1:<br />
Choosing the Appropriate Column:<br />
We recommend using the following sequence of columns to start<br />
your method development. When doing method development at<br />
Regis, the Whelk-O is our first choice as it exhibits the broadest<br />
degree of generality.<br />
Order of Preference:<br />
❍ Whelk-O<br />
❍ ULMO<br />
❍ DACH-DNB<br />
❍ α-Burke<br />
❍ β-Gem<br />
❍ Pirkle 1-J<br />
❍ Leucine<br />
❍ Phenylglycine<br />
STEP 2:<br />
Choosing the Mobile Phase:<br />
Certain factors such as solubility and future considerations for<br />
preparative work usually help to determine whether to perform<br />
you method development with reversed-phase or normal phase<br />
solvents. Pirkle-Type phases can be used in both modes, but<br />
typically performs the best with normal phase solvents. Since the<br />
majority of analytical Chiral methods move on to preparative<br />
separations, we recommend using normal phase solvents.<br />
Typical Mobile Phase Combinations:<br />
❍ Hexane/IPA ❍ Heptane/IPA<br />
❍ Hexane/Ethanol ❍ Methanol/H 2O<br />
❍ Hexane/CH 2CL 2/Ethanol ❍ Ethanol/H 2O<br />
❍ Hexane/Ethyl Acetate ❍ Acetonitrile/H 2O<br />
❍ Heptane/Ethanol ❍ Methanol/CH 2CL 2<br />
❍ Heptane/CH 2CL 2<br />
❍ Hexane/CH 2CL 2<br />
Quick Scheme Method Development<br />
FOR THE REGIS PIRKLE-TYPE CHIRAL STATIONARY PHASES<br />
❍ THF/H 2O<br />
❍ Ethanol/CH 2CL 2<br />
STEP 3:<br />
Start with a high percentage (~50%) of<br />
strong solvent (ethanol, IPA, ect.):<br />
Starting with a strong solvent system ensures that all peaks will<br />
elute off the column quickly.<br />
Sample: Naproxen<br />
Column: (R,R)-Whelk-O 1<br />

Mobile Phase: (50/50)<br />
Hexane/Ethanol<br />
Flow Rate: 1.5 mL/min<br />
Detection: UV 254 nm<br />
Run Time: 6.5 min<br />
❍ If you achieve any resolution, (such as the above sample)<br />
move on to STEP 4.<br />
❍ If your sample comes off in the void, decrease the strong<br />
solvent by half.<br />
❍ If your sample is now out of the void and you have<br />
resolution, move on to STEP 4.<br />
❍ If your sample is out of the void, and there is no resolution,<br />
change the column.<br />

Quick Scheme Method Development<br />
FOR THE REGIS PIRKLE-TYPE CHIRAL STATIONARY PHASES<br />
STEP 4:<br />
Add a Mobile Phase Modifier (usually ~ 0.1%)<br />
As you can see, the peak shape of the initial separation is very<br />
poor. To rectify this problem, a modifier is usually added. If you<br />
are satisfied with the peak shape—you do not need to add a<br />
modifier—move on to STEP 5 and optimize your separation.<br />
❍ For basic or amine groups—add triethylamine, diethylamine<br />
or ammonium acetate<br />
❍ For acidic groups—add acetic acid, trifluoroacetic acid or<br />
ammonium acetate<br />
❍ Although resolution increased with the addition of 0.1%<br />
of triethylamine to the mobile phase, the peak shape is still<br />
very poor.<br />
❍ Try adding a different modifier<br />
Recapping The First Four Steps:<br />
❍ For this sample, you can stop at 50/50 Hexane/Ethanol<br />
+ 0.1% acetic acid if you are only looking for a basic method<br />
or you can carry it forward to STEP 5 and optimize.<br />
❍ Resolution and peak shape are excellent with the addition of<br />
0.1% of acetic acid<br />
82 REGIS TECHNOLOGIES CHIRAL APPLICATION GUIDE V • WWW.REGISTECH.COM/chiral/applications
STEP 5:<br />
Optimizing your method:<br />
Optimizing a Chiral method is very similar to<br />
optimizing an achiral method. Changing mobile<br />
phase component concentrations and even the<br />
components themselves can dramatically change<br />
resolution.<br />
Increase the concentration<br />
of the weaker solvent:<br />
❍ Increasing the hexane content increased<br />
the resolution in this example. Again,<br />
you can stop here and accept this as<br />
optimized or continue on.<br />
Change the strong solvent:<br />
❍ By substituting IPA for ethanol, an<br />
increase in both resolution and alpha<br />
were achieved.<br />
Quick Scheme Method Development<br />
FOR THE REGIS PIRKLE-TYPE CHIRAL STATIONARY PHASES<br />
Optimization of a Chiral method can be as<br />
simple or as complicated as you want it to be.<br />
Different mobile phase components can be<br />
used; modifiers can be changed or eliminated;<br />
you can switch to reversed-phase solvents;<br />
you can change columns. The possibilities are<br />
endless. We suggest you keep it as simple<br />
as possible. Once you have achieved an<br />
acceptable separation, move on to the next<br />
project. Small increases in resolution and<br />
alpha are usually not worth the time spent<br />
in method development to achieve those<br />
increases.<br />
