Chemical Structure

H-Glu(Glu-OH)-OH CAS 1116-22-9 chemical structure

Description

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

CATO supplies H-Glu(Glu-OH)-OH (CAS 1116-22-9), a certified reference material (molecular formula C10H16N2O7, MW 276.24 g/mol) for analytical method development and quality control.

H-Glu(Glu-OH)-OH (C10H16N2O7) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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(Glu-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.
