Chemical Structure

H-D-Ala-Gly-Gly-OH CAS 77286-90-9 chemical structure

Description

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

H-D-Ala-Gly-Gly-OH (CAS 77286-90-9), molecular formula C7H13N3O4 and molecular weight 203.20 g/mol, is a CATO reference standard with documented purity and traceability.

H-D-Ala-Gly-Gly-OH (C7H13N3O4) 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.
