Abstract
An optical resolver comprising an optically active substance made of tris-(2,3-epoxypropyl)isocyanurate, is presented. The optical resolver comprises an optically active tris-(epoxyalkyl)isocyanurate or its derivative, or an optically active derivative of a tris-(epoxyalkyl)isocyanurate. Particularly, the optical resolver comprises optically active tris-(2,3-epoxypropyl)isocyanurate or its derivative, or an optically active derivative of tris-(2,3-epoxypropyl)isocyanurate. Having supported on a carrier, an optically active tris-(2,3-epoxypropyl)isocyanurate or its derivative, or an optically active derivative of tris-(2,3-epoxypropyl)isocyanurate, can be made to be a packing for use in high-performance liquid chromatography, whereby efficient optical resolution can be carried out.
