Chemical Structure

H-Met-Arg-Phe-OH CAS 67368-25-6 chemical structure

Description

CATO manufactures H-Met-Arg-Phe-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.

CATO supplies H-Met-Arg-Phe-OH (CAS 67368-25-6), a certified reference material (molecular formula C20H32N6O4S, MW 452.57 g/mol) for analytical method development and quality control.

The molecular framework of H-Met-Arg-Phe-OH (C20H32N6O4S) is characterized by a flavonoid core, an amide group, a sulfone 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 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.
