Chemical Structure

Finerenone Impurity 85 CAS CATO-C4X-288085 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 325.36 g/mol gives Finerenone Impurity 85 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Finerenone Impurity 85 (CAS CATO-C4X-288085), a pharmacopoeial impurity reference standard (molecular formula C18H19N3O3, MW 325.36 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Finerenone Impurity 85 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 325.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.

As a certified reference material (CRM), Finerenone Impurity 85 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
