Description
CATO manufactures Revefenacin Impurity 53 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies Revefenacin Impurity 53 (CAS CATO-C4X-203153), a pharmacopoeial impurity reference standard (molecular formula C29H31N3O4CH2O2, MW 531.61 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Revefenacin Impurity 53 (C29H31N3O4CH2O2) is characterized by a steroid core, an amide 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 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.
