Chemical Structure

H-Gly-Trp-Gly-OH CAS 23067-32-5 chemical structure

Description

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

CATO supplies H-Gly-Trp-Gly-OH (CAS 23067-32-5), a certified reference material (molecular formula C15H18N4O4, MW 318.33 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, H-Gly-Trp-Gly-OH is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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