Abstract: A new type of partially substituted cyclodextrin-bonded silica particles, phenylcarbamate-(3-(2-O-β-cyclodextrin)-2-hydroxypropoxy)-propylsilyl-appended silica (P-CD-HPS), has been successfully prepared and used as chiral stationary phase (CSP) in high-performance liquid chromatog. (HPLC) under normal-phase, reversed-phase, and polar organic mobile-phase conditions. The P-CD-HPS was characterized by elemental anal. and Fourier transform IR spectroscopic (FTIR) anal. The chromatog. performance of the new-phase P-CD-HPS has been evaluated in HPLC under multi-mode conditions via separating positional isomers of some disubstituted benzenes and enantiomers of some chiral drug compounds The separation results show that P-CD-HPS exhibited excellent selectivity for separating the positional isomers of nitrophenol and nitraniline and the enantiomers of some chiral drug compounds The hydroxyl residues of partially substituted β-cyclodextrin and chiral spacer linking to secondary hydroxyl site of the β-cyclodextrin in the P-CD-HPS not only have important contributions to chiral recognitions and separations, but also allow the P-CD-HPS to be used under multi-mode mobile-phase conditions in HPLC.
