Chemical Structure

H-Gly-Phe-AMC CAS 201852-70-2 chemical structure

Description

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

H-Gly-Phe-AMC (CAS 201852-70-2), molecular formula C21H21N3O4 and molecular weight 379.41 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of H-Gly-Phe-AMC (C21H21N3O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), H-Gly-Phe-AMC meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
