Abstract:
In this work, a detail study has been performed on the enantioselectivity of per(3-chloro-4-methyl)phenylcarbamate-β-CD clicked chiral stationary phase (CSP) in high-performance liquid chromatography. Both normal phase and polar organic mobile phases have been explored for the enantioseparation of 39 model racemic pairs including aromatic alcohols, flavonoids, β-blockers and amino acids. Chiral resolution values over 10 were achieved for flavonoids. The comparison study with reference perphenylcarbamate-β-CD clicked CSP reveals the significance of 3-chloro-4-methyl functionality in improving the enantioselectivities. This study may provide insight on the multiple interactions between functionalized CD and analytes.

Chromatography: Introduction
The phase in which the compounds linger or on which the compounds adsorb is called the stationary phase, whereas the mobile phase is the solvent that carries the solutes to be analyzed. In traditional column chromatography, the mixture flows through the stationary phase, and the compounds partition between the stationary and mobile phases...
