Chemical Structure
Description
Based on its molecular formula C14H9FOS, Baloxavir Marboxil Impurity 235 contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 244.28 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 Marboxil Impurity 235 (CAS CATO-C4X-2108235), a pharmacopoeial impurity reference standard (molecular formula C14H9FOS, MW 244.28 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.
