Chemical Structure

Benzbromarone Impurity 33 CAS CATO-C4X-225033 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benzbromarone Impurity 33.

CATO supplies Benzbromarone Impurity 33 (CAS CATO-C4X-225033), a pharmacopoeial impurity reference standard (molecular formula C8H6Cl2O2, MW 205.04 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Benzbromarone Impurity 33 (C8H6Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 205.04 g/mol, it falls into the medium-molecular-weight range. 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.

CATO manufactures Benzbromarone Impurity 33 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.
