Lornoxicam Impurity 19 Sodium Salt CAS CATO-C4X-201619

Description

CATO supplies Lornoxicam Impurity 19 Sodium Salt (CAS CATO-C4X-201619), a pharmacopoeial impurity reference standard (molecular formula C9H11ClNO6S2Na, MW 351.75 g/mol) used for the identification and quantification of trace impurities in APIs.

Lornoxicam Impurity 19 Sodium Salt (C9H11ClNO6S2Na) contains a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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), Lornoxicam Impurity 19 Sodium Salt 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.
