(57) [Summary] [Formula 1] (R 1 is an alkyl group, R 2 is an alkylene group, 1 is 0 or 1, and * is the position of the asymmetric carbon), and is an optically active 4,5-diphenyl-2-imidazolidinone derivative. A method for analyzing optical purity of amines having an asymmetric carbon used and a reagent for analysis. [Effect] By using this compound (1), the optical purity of amines having an asymmetric carbon can be accurately analyzed and determined by a simple operation. |
