Separation of piracetam derivatives on polysaccharide-based chiral stationary phases

Journal of Chromatography A, 2013
High-performance liquid chromatography was used for the enantiomeric separation of two chiral piracetam derivatives. The suitability of six commercially available polysaccharide-based chiral stationary phases (CSPs) under normal phase mode for direct enantioseparation has been investigated. The influence of the CSPs as well the nature and content of an

Enantiomer resolution screening strategy using multiple immobilised polysaccharide-based chiral stationary phases

Journal of Chromatography A, 2008
CHIRALPAK IA, CHIRALPAK IB and CHIRALPAK IC are a new generation of chiral packing materials for resolution of enantiomers by chromatography. They are all prepared by chemical immobilisation of the respective polysaccharide derivatives onto a supporting silica matrix. The present article aims to establish an understanding of the global enantioselective

Polysaccharide-based chiral stationary phases for high-performance liquid chromatographic enantioseparation

Journal of Chromatography A, 2001
Recent developments of polysaccharide-based chiral stationary phases (CSPs) for the direct separation of enantiomers in high-performance liquid chromatography (HPLC) are mainly reviewed together with the results on mechanistic studies by means of chromatography, NMR and mass spectroscopies, and computational methods.

Recent developments on polysaccharide-based chiral stationary phases for liquid-phase separation of enantiomers

Journal of Chromatography A, 2012
This paper summarizes recent developments in the synthesis, application and mechanistic studies on polysaccharide-based chiral stationary phases (CSPs) for liquid phase separation techniques. Together with applications in conventional high-performance liquid chromatography (HPLC) applications in nano-liquid chromatography (nano-LC), capillary ...

Pharmaceutical-enantiomers resolution using immobilized polysaccharide-based chiral stationary phases in supercritical fluid chromatography

Journal of Chromatography A, 2014
Since their introduction on the market the applicability of immobilized polysaccharide-based chiral stationary phases in high-performance liquid chromatography has been thoroughly investigated. These immobilized phases have the benefit to be applicable with a wide range of modifiers, potentially extending the application range of the polysaccharide ...

Chromatographic Enantioseparation of Chiral Sulfoximines on Polysaccharide-Based Chiral Stationary Phases

Journal of Chromatographic Science, 2023
Abstract Chiral sulfoximines have significant roles in pharmaceutical industry and agricultural chemicals. Furthermore, chiral structurally related sulfoximines are used for their wide potential applications in some uncharted territory. However, chromatographic study on these compounds has not been systematically performed.

Chromatographic enantioseparation of chiral sulfinamide derivatives on polysaccharide-based chiral stationary phases

Journal of Chromatography A, 2018
Chiral sulfinamides are increasingly recognizedfor their extensive potential applications in chemistry, medicine and material science, yet chromatographic study on these compounds is seldom. In this article, we describe the enantioseparation of twelve closely related chiral sulfinamide derivatives on polysaccharide-based chiral stationary phases (CSPs).
