Description
CATO supplies Toceranib impurity 2 (CAS CATO-C4X-25852), a pharmacopoeial impurity reference standard (molecular formula C22H25FN4O3, MW 412.46 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C22H25FN4O3, Toceranib impurity 2 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 412.46 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
