Description
As a certified reference material (CRM), Lornoxicam Impurity 79 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.
CATO supplies Lornoxicam Impurity 79 (CAS 1629463-16-6), a pharmacopoeial impurity reference standard (molecular formula C10H11NO6S2, MW 305.33 g/mol) used for the identification and quantification of trace impurities in APIs.
Lornoxicam Impurity 79 (C10H11NO6S2) 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 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.
