Chemical Structure

H-Phe-Gly-Phe-Gly-OH CAS 59005-83-3 chemical structure

Description

The occurrence of H-Phe-Gly-Phe-Gly-OH is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

H-Phe-Gly-Phe-Gly-OH (CAS 59005-83-3), molecular formula C22H26N4O5 and molecular weight 426.47 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, H-Phe-Gly-Phe-Gly-OH is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 426.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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

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