Immobilized-type chiral packing materials for HPLC based on polysaccharide derivatives

Hybrid monolithic columns coated with cellulose tris(3,5-dimethylphenyl-carbamate) for enantioseparations in capillary electrochromatography and capillary liquid chromatography

“…Polysaccharide derivatives have occupied a unique place among these chiral stationary phases (CSPs) and have been the most widely used chiral selector for enantioseparation of a broad range of chiral compounds [21][22][23][24]. Several kinds of polysaccharide derivatives such as cellulose tris(3,5-dimethylphenylcarbamate) (CDMPC), cellulose tris(4-methylbenzoate), cellulose tris(3,5-dichlorophenyl carbamate) and amylose tris(3,5-dimethylphenylcarbamate) have been coated or immobilized onto the silica-based monoliths and successfully applied for enantioseparations in CLC or CEC [25,26,27,28,29].…”

The Development and Application of Cellulose-Based Stationary Phases in Stereoselective Separation of Chiral Pesticides

“…Ikai et al summarized various immobilization methods of the polysaccharide derivatives mainly onto silica gel: immobilization using diisocyanate, vinyl groups by polymerization and copolymerization with a vinyl monomer etc. [28,29]. Several methods of synthesis are shown in Figures 2 to 4.…”

Fases estacionárias quirais para cromatografia líquida de alta eficiência

“…63 Desde então, várias CSPs de polissacarídeos quimicamente ligadas têm sido desenvolvidas. 40,[64][65][66][67] A literatura relata diversos métodos de preparo das CSPs de polissacarídeos imobilizadas por ligação covalente direta do seletor quiral ao suporte 62,63,68 ou pela reticulação do polissacarídeo, previamente imobilizado no suporte, por ligações intercruzadas. [69][70][71][72] Algumas técnicas de imobilização combinam as duas estratégias.…”
