Chemical Structure

Dotinurad Impurity 214 CAS CATO-C4X-2494214 chemical structure

Description

The occurrence of Dotinurad Impurity 214 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Dotinurad Impurity 214 (CAS CATO-C4X-2494214), a pharmacopoeial impurity reference standard (molecular formula C9H7ClO4, MW 214.60 g/mol) used for the identification and quantification of trace impurities in APIs.

Dotinurad Impurity 214 (C9H7ClO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Dotinurad Impurity 214 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.
