Acetylcysteine Impurity 70 Sodium Salt CAS CATO-C4X-153270 chemical structure

Description

CATO manufactures Acetylcysteine Impurity 70 Sodium Salt 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.

Acetylcysteine Impurity 70 Sodium Salt (CAS CATO-C4X-153270) is a certified pharmaceutical impurity reference standard with the molecular formula C5H6NO2SNa and a molecular weight of 167.16 g/mol.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Acetylcysteine Impurity 70 Sodium Salt is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 167.16 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).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
