Finerenone Impurity 142 CAS CATO-C4X-2880142

Description

The occurrence of Finerenone Impurity 142 is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Finerenone Impurity 142 (CAS CATO-C4X-2880142) is a certified pharmaceutical impurity reference standard with the molecular formula C25H26N4O4 and a molecular weight of 446.50 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Finerenone Impurity 142 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 446.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Finerenone Impurity 142 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.
