Description
CATO supplies Ozenoxacin Impurity 26 (CAS CATO-C4X-279626), a pharmacopoeial impurity reference standard (molecular formula C27H25N3O4, MW 455.51 g/mol) used for the identification and quantification of trace impurities in APIs.
Ozenoxacin Impurity 26 (C27H25N3O4) contains a steroid core, an amide 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), Ozenoxacin Impurity 26 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.
