Abstract
The present invention provides a separating agent for enantiomeric isomers which exhibits high optical resolving power together with solvent resistance. That is, the present invention provides a separating agent for enantiomeric isomers including a polysaccharide derivative such as a carbamate derivative or ester derivative of cellulose or amylose carried on a porous carrier such as silica gel, in which the porous carrier having an epoxy group and part of hydroxyl groups of the polysaccharide derivative are chemically bonded.
