Chemical Structure

H-D-Asn(Trt)-OH CAS 200192-49-0 chemical structure

Description

H-D-Asn(Trt)-OH (CAS 200192-49-0), molecular formula C23H22N2O3 and molecular weight 374.43 g/mol, is a CATO reference standard with documented purity and traceability.

H-D-Asn(Trt)-OH (C23H22N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures H-D-Asn(Trt)-OH under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
