Title:
PREPARATION OF CHROMATOGRAPHIC STATIONARY PHASE HAVING POROUS FRAMEWORK MATERIAL AS MATRIX FOR CHIRAL SEPARATION
Document Type and Number:
WIPO Patent Application WO/2019/137251
Kind Code:
A1
Abstract:
A novel porous framework material (such as a metal organic framework material or a covalent organic framework material) having a wide range of applications was designed and developed in an inventive manner to resolve issues with respect to a carrier material in a stationary phase of a conventional chiral chromatographic column in which the carrier material has poor stability, a chiral resolving agent has a low loading rate, and the chiral resolving agent is prone to loss or is applied in a restricted manner. The porous framework material efficiently loads a chiral resolving agent (such as proteins, enzymes, or macrocyclic antibiotics) by means of covalent bonding, adsorption, embedding, and crosslinking, such that a variety of efficient and durable chiral stationary phases are prepared to serve as a novel high-performance chromatographic column filler used for chromatographic chiral separation (such as high-performance liquid chromatography or capillary chromatography). The various chiral stationary phases prepared by applying the above technique have high separation efficiency, high stability, and durability, and have been successfully applied to perform efficient separation of different kinds of chiral materials such as chiral amino acids and a chiral drug. The technique greatly widens the application range and extends the service life of a chiral chromatographic separation column.
