Description
Finerenone Impurity 141 (CAS CATO-C4X-2880141) is a certified pharmaceutical impurity reference standard with the molecular formula C20H19N3O4 and a molecular weight of 365.38 g/mol.
Based on its molecular formula C20H19N3O4, Finerenone Impurity 141 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 365.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
CATO manufactures Finerenone Impurity 141 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.
