Finerenone Impurity 237 CAS CATO-C4X-2880237

Description

Compared with other compounds in its class, the molecular weight of 191.25 g/mol gives Finerenone Impurity 237 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Finerenone Impurity 237 (CAS CATO-C4X-2880237), a pharmacopoeial impurity reference standard (molecular formula C7H8N2O2K, MW 191.25 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Finerenone Impurity 237 (C7H8N2O2K) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 191.25 g/mol, it falls into the medium-molecular-weight range. 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 237 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.
