CATO supplies H-Gly-Gly-Phe-Phe-OEt (CAS 22732-97-4), a certified reference material (molecular formula C24H30N4O5, MW 454.52 g/mol) for analytical method development and quality control.
The molecular framework of H-Gly-Gly-Phe-Phe-OEt (C24H30N4O5) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
