D-Aspartic Acid CAS 1783-96-6 chemical structure

Description

CATO manufactures D-Aspartic Acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

D-Aspartic Acid (CAS 1783-96-6) is a high-purity analytical reference standard with the molecular formula C4H7NO4 and a molecular weight of 133.10 g/mol.

D-Aspartic Acid (C4H7NO4) contains a carbohydrate-derived structure, an amide group. 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.
