Chemical Structure

Bumetanide Impurity 73 CAS CATO-C4X-198673 chemical structure

Description

CATO supplies Bumetanide Impurity 73 (CAS CATO-C4X-198673), a pharmacopoeial impurity reference standard (molecular formula C7H6ClN3O5S, MW 279.66 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C7H6ClN3O5S, Bumetanide Impurity 73 contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 279.66 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 Bumetanide Impurity 73 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.
