Eplerenone Impurity 42 CAS CATO-C4X-163042

Description

The occurrence of Eplerenone Impurity 42 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.

Eplerenone Impurity 42 (CAS CATO-C4X-163042) is a certified pharmaceutical impurity reference standard with the molecular formula C25H29NO6 and a molecular weight of 439.50 g/mol.

Based on its molecular formula C25H29NO6, Eplerenone Impurity 42 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 439.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Eplerenone Impurity 42 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.
