Chemical Structure

H-Ser-Tyr-AMC CAS 201855-53-0 chemical structure

Description

H-Ser-Tyr-AMC (CAS 201855-53-0), molecular formula C22H23N3O6 and molecular weight 425.43 g/mol, is a CATO reference standard with documented purity and traceability.

H-Ser-Tyr-AMC (C22H23N3O6) contains a flavonoid 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures H-Ser-Tyr-AMC 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.
