Esaxerenone Impurity 4 CAS CATO-C4X-34484 chemical structure

Description

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.

Esaxerenone Impurity 4 (CAS CATO-C4X-34484) is a certified pharmaceutical impurity reference standard with the molecular formula C9H9NO5S and a molecular weight of 243.24 g/mol.

Based on its molecular formula C9H9NO5S, Esaxerenone Impurity 4 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 243.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures Esaxerenone Impurity 4 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.
