Chemical Structure
Description
The occurrence of L-Aspartic aicd (disodium) is closely related to a carbohydrate-derived structure, an amide group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
L-Aspartic aicd (disodium) (CAS 5598-53-8), molecular formula C4H5NNa2O4 and molecular weight 177.07 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, an amide group, L-Aspartic aicd (disodium) is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 177.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
