Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 349.38 g/mol gives Finerenone Impurity 113 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Finerenone Impurity 113 (CAS CATO-C4X-2880113) is a certified pharmaceutical impurity reference standard with the molecular formula C20H19N3O3 and a molecular weight of 349.38 g/mol.
Finerenone Impurity 113 (C20H19N3O3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Finerenone Impurity 113 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.
