Chemical Structure
Description
CATO manufactures L-Arginine DL-Malate(2:1) 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.
L-Arginine DL-Malate(2:1) (CAS 39064-57-8) is a high-purity analytical reference standard with the molecular formula C6H14N4O2C4H6O5 and a molecular weight of 308.29 g/mol.
L-Arginine DL-Malate(2:1) (C6H14N4O2C4H6O5) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
