Chemical Structure

H-Glu(Met-OH)-OH CAS 17663-87-5 chemical structure

Description

The occurrence of H-Glu(Met-OH)-OH is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies H-Glu(Met-OH)-OH (CAS 17663-87-5), a certified reference material (molecular formula C10H18N2O5S, MW 278.33 g/mol) for analytical method development and quality control.

Based on its molecular formula C10H18N2O5S, H-Glu(Met-OH)-OH contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 278.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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-Glu(Met-OH)-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.
