Chemical Structure
Description
CATO supplies Finerenone Impurity 253 (CAS CATO-C4X-2880253), a pharmacopoeial impurity reference standard (molecular formula C22H25N3O5, MW 411.45 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Finerenone Impurity 253 (C22H25N3O5) is characterized by a flavonoid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures Finerenone Impurity 253 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.
