Chemical Structure
Description
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 supplies Baloxavir Marboxil Impurity 205 (CAS CATO-C4X-2108205), a pharmacopoeial impurity reference standard (molecular formula C14H8F2OS, MW 262.27 g/mol) used for the identification and quantification of trace impurities in APIs.
Baloxavir Marboxil Impurity 205 (C14H8F2OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures Baloxavir Marboxil Impurity 205 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.
