Chemical Structure

Erdosteine Impurity 1 Sodium Salt(Mixture of Diastereomers) CAS CATO-C4X-19631 chemical structure

Description

The occurrence of Erdosteine Impurity 1 Sodium Salt(Mixture of Diastereomers) is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Erdosteine Impurity 1 Sodium Salt(Mixture of Diastereomers) (CAS CATO-C4X-19631), a pharmacopoeial impurity reference standard (molecular formula C12H17N2O5S3Na, MW 388.45 g/mol) used for the identification and quantification of trace impurities in APIs.

Erdosteine Impurity 1 Sodium Salt(Mixture of Diastereomers) (C12H17N2O5S3Na) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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 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.

As a certified reference material (CRM), Erdosteine Impurity 1 Sodium Salt(Mixture of Diastereomers) 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.
