Chemical Structure

H-Ala-Phe-Ala-OH CAS 54865-19-9 chemical structure

Description

As a certified reference material (CRM), H-Ala-Phe-Ala-OH 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.

H-Ala-Phe-Ala-OH (CAS 54865-19-9) is a high-purity analytical reference standard with the molecular formula C15H21N3O4 and a molecular weight of 307.34 g/mol.

The molecular framework of H-Ala-Phe-Ala-OH (C15H21N3O4) 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.
