Baloxavir Impurity 23 CAS CATO-C4X-210823 chemical structure

Description

CATO manufactures Baloxavir Impurity 23 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.

CATO supplies Baloxavir Impurity 23 (CAS CATO-C4X-210823), a pharmacopoeial impurity reference standard (molecular formula C15H12F2O3S2, MW 342.38 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C15H12F2O3S2, Baloxavir Impurity 23 contains a sulfone group, a carboxylic acid group, 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 342.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
