Chemical Structure

Eplerenone Impurity 17 CAS CATO-C4X-163017 chemical structure

Description

As a certified reference material (CRM), Eplerenone Impurity 17 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.

CATO supplies Eplerenone Impurity 17 (CAS CATO-C4X-163017), a pharmacopoeial impurity reference standard (molecular formula C24H31O6Na, MW 438.50 g/mol) used for the identification and quantification of trace impurities in APIs.

Eplerenone Impurity 17 (C24H31O6Na) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
