Chemical Structure

Benzbromarone Impurity 32 CAS CATO-C4X-225032 chemical structure

Description

The occurrence of Benzbromarone Impurity 32 is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Benzbromarone Impurity 32 (CAS CATO-C4X-225032), a pharmacopoeial impurity reference standard (molecular formula C18H16O3, MW 280.32 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C18H16O3, Benzbromarone Impurity 32 contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 280.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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 Benzbromarone Impurity 32 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.
