(57) [Summary] [Object] To provide a packing material for separating an optical isomer mixture of amino acids by a chromatography method, and a compound for producing the same. [Structure] General formula: [Wherein R 1 and R 2 are alkyl groups (which may include an unsaturated bond and an aromatic group as a substituent), or R 1 is the same as the above formula (I) except R 1 R 2 in the resulting group Is as defined above, or R 1 and R 2 together represent an alkanediyl group, R 3 is hydrogen or an alkyl group (including an unsaturated bond and an aromatic group as a substituent) Also means). However, the total number of carbon atoms of R 1 , R 2 and R 3 is 8 or more] and a separating agent obtained by coating a carrier with the above compound. |
