Description
CATO supplies Sunitinib Impurity 79 (CAS CATO-C4X-133379), a pharmacopoeial impurity reference standard (molecular formula C24H14F3N3O3, MW 449.38 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Sunitinib Impurity 79 (C24H14F3N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 449.38 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures Sunitinib Impurity 79 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.
