(57) [Summary] [Structure] A substituted aromatic carbamate derivative of a polysaccharide in which 80% to 100% of the hydroxyl groups of the polysaccharide are substituted with a group represented by the following general formula (1), and a substituted aromatic carbamate of the polysaccharide. A separating agent containing a derivative as an active ingredient. [Chemical 1] (In the formula, R 1 , R 2 , R 3 , R 4 and R 5 are each a hydroxyl atom or an alkyl group having 1 to 8 carbon atoms or a halogen atom, and at least two of R 1 to R 5 are It is an alkyl group having 1 to 8 carbon atoms or a halogen atom, and is a different substituent.) [Effect] The separating agent of the present invention is effective for separating various compounds, and in particular, optical separation has been very difficult in the past. It is extremely effective in separating isomers. |
