ABSTRACT:
The present invention provides a separating agent for enantiomeric isomers having no large UV absorption, as represented by an aromatic group, and having high asymmetric recognizability, particularly, high asymmetric recognizability in an aqueous mobile phase, or a separating agent for enantiomeric isomers containing a polysaccharide alicyclic ester derivative free from an aromatic group as an effective component.
