Chemical Structure
Description
CATO supplies Cefuroxime Impurity 32 (CAS CATO-C4X-124532), a pharmacopoeial impurity reference standard (molecular formula C15H15N3O8SNa, MW 420.35 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Cefuroxime Impurity 32 (C15H15N3O8SNa) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Cefuroxime 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.
