Description
CATO supplies Meloxicam Impurity 1 (CAS 892395-41-4), a pharmacopoeial impurity reference standard (molecular formula C15H15N3O4S2, MW 365.43 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Meloxicam Impurity 1 (C15H15N3O4S2) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Meloxicam Impurity 1 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.
