(57) [Summary] [Objective] To provide a packing material for separating a mixture of optical isomers by a liquid chromatography method. [Structure] General formula (I) [In the formula, * represents an asymmetric carbon. R 1 represents a lower alkyl group, a monocyclic aryl lower alkyl group, a lower alkoxy-substituted monocyclic aryl lower alkyl group or a lower cycloalkyl lower alkyl group. R 2 represents a monocyclic aryl group having a lower alkoxy or a monocyclic aryl lower alkoxy as a substituent. X 1 and X 2 each represent a hydrogen atom or a halogen atom, or together represent a group —CH 2 —CH═CH—CH 2 —] and a complex of a Schiff base and copper (II). A separating agent for liquid chromatography, which is formed by coating a reverse phase carrier. |
