Chemical Structure

L-γ-Glutamyl-L-cysteinyl-L-lysine CAS 128960-73-6 chemical structure

Description

The occurrence of L-γ-Glutamyl-L-cysteinyl-L-lysine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies L-γ-Glutamyl-L-cysteinyl-L-lysine (CAS 128960-73-6), a certified reference material (molecular formula C14H26N4O6S, MW 378.44 g/mol) for analytical method development and quality control.

L-γ-Glutamyl-L-cysteinyl-L-lysine (C14H26N4O6S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), L-γ-Glutamyl-L-cysteinyl-L-lysine 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.
