Title:
SEPARATING AGENT FOR CHROMATOGRAPHY
Document Type and Number:
WIPO Patent Application WO/2012/050124
Kind Code:
A1
Abstract:
Provided is a separating agent for chromatography useful for the separation of a specific compound such as optical resolution of amino acid, the separating agent having a higher productivity and containing binaphthyl that has a crown ether-like cyclic structure and an optical activity. Provided is a specific separating agent for chromatography which contains binaphthyl having a crown ether-like cyclic structure and an optical activity by introducing a carrier linking group into a specific 1,1'-binaphthyl derivative that is commercially available and has substituents at positions 2, 2', 3, and 3', then introducing a crown ether-like cyclic structure, and then chemically binding the binaphthyl derivative and carrier by using the carrier linking group.
