Description
CATO supplies Flomoxef Impurity 29 (CAS 2095697-75-7), a pharmacopoeial impurity reference standard (molecular formula C15H20F2N6O8S2, MW 514.48 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C15H20F2N6O8S2, Flomoxef Impurity 29 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 514.48 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 Flomoxef Impurity 29 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.
