Abstract: Heptakis(6-azido-6-deoxy) perphenylcarbamated β-cyclodextrin has been synthesized and chemically immobilized on silica gel for use as a chiral stationary phase (PC-CSP) for analytical separation of the enantiomers of chiral drugs. Separation of the enantiomers of tolperisone was studied by high-performance liquid chromatography under reversed-phase conditions. The chromatographic conditions were optimized by varying mobile phase pH, composition, ionic strength, and velocity; 40:60 methanol-1% triethylammonium acetate (TEAA) buffer, pH 5.5, was found to be the most suitable for this separation.
