PURPOSE:To make it possible to perform optical splitting, by providing a chiral carbamoyl hydroxy-carboxylic amide residue represented by a specific formula. CONSTITUTION:A chiral fixing phase for chromatography is one chemically bonded to a substrate having a chiral carbamoyl hydroxycarboxylic amide residue represented by formula I (wherein R1, R2 and R3 are pref. a hydrogen atom, an 1-6C straight chain or branched alkyl group, a phenyl group, a naphthyl group or an anthryl group and n is an integer of 1-6). |
