Description
CATO manufactures Isavuconazole Impurity 83 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.
CATO supplies Isavuconazole Impurity 83 (CAS CATO-C4X-123683), a pharmacopoeial impurity reference standard (molecular formula C39H45F2N8O6SHO4S, MW 888.96 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C39H45F2N8O6SHO4S, Isavuconazole Impurity 83 contains a nitrogen-containing heterocyclic scaffold, 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 888.96 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
