## Abstract Crown etherβbased chiral stationary phases (CSPs) have been known to be quite useful for the liquid chromatographic resolution of racemic compounds containing a primary amino group. Chiral separations on crown etherβbased CSPs are characterized by several factors. In this paper, the str
