The problem addressed by the present invention is to provide a novel separating agent for hydrophilic interaction chromatography useful in separating hydrophilic compounds. The hydrophilic interaction chromatography separating agent, which is formed from a carrier and a ligand carried by the carrier, is a separating agent wherein the ligand is a (meth)acrylic polymer having a constituent unit derived from the compound indicated by formula (I). (In formula (I): there are one or two double bonds between atoms configuring a heterocycle; X1 is selected from the group consisting of S, SCH3 +, O, NH, NCH3, CH2, CHR, and CR1R2; and X2, X3, and X4 are each selected from the group consisting of N, NH, NCH3, CH2, CHR, NCH3 +, CH, CR, and CR1R2. R1 and R2 are each a substituted or unsubstituted alkyl having 1-18 carbon atoms, an aryl having 6-18 carbon atoms, an alkenyl having 2-18 carbon atoms, an alkynyl having 2-18 carbon atoms, an aralkyl having 7-18 carbon atoms, an acyl having 2-18 carbon atoms, a cycloalkyl having 3-18 carbon atoms, a carboxyl, an amino, an aryloxy having 6-18 carbon atoms, an alkoxy having 1-18 carbon atoms, a halo, a hydroxy, a nitro, or a cyano. R is a substituted or unsubstituted alkyl having 1-18 carbon atoms, an aryl having 6-18 carbon atoms, an alkenyl having 2-18 carbon atoms, an alkynyl having 2-18 carbon atoms, an aralkyl having 7-18 carbon atoms, an acyl having 2-18 carbon atoms, a cycloalkyl having 3-18 carbon atoms, a carboxyl, an amino, an aryloxy having 6-18 carbon atoms, an alkoxy having 1-18 carbon atoms, a halo, a hydroxy, a nitro, or a cyano. At least two of X1, X2, X3, and X4 are not CH2, CH, CR, or CR1R2, and R3 is H or CH3.) |
