Chemical Structure

H-Gly-Arg-Gly-Glu-Ser-Pro-OH CAS 99896-88-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including H-Gly-Arg-Gly-Glu-Ser-Pro-OH.

CATO supplies H-Gly-Arg-Gly-Glu-Ser-Pro-OH (CAS 99896-88-5), a certified reference material (molecular formula C23H39N9O10, MW 601.61 g/mol) for analytical method development and quality control.

The molecular framework of H-Gly-Arg-Gly-Glu-Ser-Pro-OH (C23H39N9O10) 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).

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-Gly-Arg-Gly-Glu-Ser-Pro-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.
