Chemical Structure
Description
Based on its molecular formula C30H31F2N3O4SCH4O3S, Baloxavir impurity 1048 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 663.75 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.
CATO supplies Baloxavir impurity 1048 (CAS 2136287-70-0), a pharmacopoeial impurity reference standard (molecular formula C30H31F2N3O4SCH4O3S, MW 663.75 g/mol) used for the identification and quantification of trace impurities in APIs.
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.
