Description
CATO supplies Dasatinib Impurity 64 (CAS 2468737-75-7), a pharmacopoeial impurity reference standard (molecular formula C22H25Cl2N7O2S, MW 522.45 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C22H25Cl2N7O2S, Dasatinib Impurity 64 contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 522.45 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.
CATO manufactures Dasatinib Impurity 64 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.
