Preparation and enantioseparation property of chiral stationary phases based on cellulose tris(3,5-dimethylbenzoate) - A new way to prepare polysaccharide-coating type chiral stationary phases

, 2014
A new method to prepare polysaccharide-coating type chiral stationary phases (CSPs) was developed in this work. As a typical example, naked silica gel was coated by cellulose, which was then derivatized with 3,5-dimethylbenzoyl chloride to afford ...

Enantioseparation of selected FMOC-derivatized amino acids on Chirobiotic T a Chiralpak QD-AX columns.

, 2015
In this work, an enantioselective HPLC method with fluorimetric detection (λEx = 254 nm, λEm = 314 nm) was developed and subsequently optimized for chiral separation of four amino acids (D/L-alanine, D/L-valine, D/L-leucine, D/L-isoleucine) in ...

The preparation of norvancomycin-bonded chiral stationary phase and its application on the enantioseparation of benproperine phosphate

, 2004
Norvancomycin-bonded chiral stationary phase ( NVC-CSP) and phenyl carbamate-derivatized norvancomycin-bonded chiral stationary phase (PC-NVC-CSP) were synthesized, and used for the enantioseparation of benproperine phosphate in polar organic phase mode ...
