Separation of enantiomers: needs, challenges, perspectives.
Chiral drugs, agrochemicals, food additives and fragrances represent classes of compounds with high economic and scientific potential. First the present implications of their chiral nature andExpand
Cellulose 3,5-dimethylphenylcarbamate immobilized on silica A new chiral stationary phase for the analysis of enantiomers
Abstract Recently, we have reported the solvent versatility and enantiomeric resolution performance of an immobilized amylose derivative-based chiral stationary phase (CSP), CHIRALPAK ® IA. TheExpand
Reversed-phase screening strategies for liquid chromatography on polysaccharide-derived chiral stationary phases.
Immobilised polysaccharide-based chiral stationary phases (CSPs) are chromatographic materials that combine the remarkable enantioselective performance of the polysaccharide derivatives in additionExpand
Enantiomeric separation of drugs and herbicides on a beta-cyclodextrin-bonded stationary phase.
A chemically bonded beta-cyclodextrin chiral stationary phase for HPLC was prepared in a "one pot" process by the reaction of a phenylated beta-cyclodextrin with silica gel. Various racemic analytesExpand
Solvent versatility of immobilized 3,5-dimethylphenylcarbamate of amylose in enantiomeric separations by HPLC.
CHIRALPAK IA is a new chiral stationary phase containing amylose 3.5-dimethylphenylcarbamate immobilized onto silica gel. It is compatible with the whole range of organic solvents. Its solventExpand
Covalently bonded polysaccharide derivatives as chiral stationary phases in high-performance liquid chromatography.
Polysaccharide derivatives have been extensively used as chromatographic chiral selectors in chiral stationary phases (CSPs) for the separation of enantiomers by HPLC. When coated onto a silicaExpand
3,5-Dimethylphenylcarbamates of amylose, chitosan and cellulose bonded on silica gel: Comparison of their chiral recognition abilities as high-performance liquid chromatography chiral stationary
Mixed 10-undecenoyl/3,5-dimethylphenylaminocarbonyl derivatives of amylose and chitosan were prepared and immobilized on allylsilica gel. The enantioselectivities of the resulting supports wereExpand
Method development and optimization on cinchona and chiral sulfonic acid-based zwitterionic stationary phases for enantiomer separations of free amino acids by high-performance liquid chromatography.
CHIRALPAK ZWIX(+) and ZWIX(-) are cinchona alkaloid-derived zwitterionic chiral stationary phases (CSPs) containing a chiral sulfonic acid motif which serves as negatively charged interaction site.Expand
Solvent versatility of bonded cellulose-derived chiral stationary phases for high-performance liquid chromatography and its consequences in column loadability
The chromatographic behaviour of a 10-undecenoate/3,5-dimethylphenylcarbamate of cellulose bonded on allylsilica gel is tested using four organic mobile-phase modifiers (2-propanol, chloroform,Expand
Carbamates of cellulose bonded on silica gel: Chiral discrimination ability as HPLC chiral stationary phases
Four cellulose mixed 10-undecenoate/carbamate derivatives, simultaneously bearing 10-undecenoyl and variously substituted phenylaminocarbonyl groups, were chemically bonded on allylsilica gel. TheExpand
