Chemical Structure
Description
The occurrence of Baloxavir Marboxil Impurity 174 is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Baloxavir Marboxil Impurity 174 (CAS CATO-C4X-2108174) is a certified pharmaceutical impurity reference standard with the molecular formula C26H20ClF2N3O5S and a molecular weight of 559.97 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Baloxavir Marboxil Impurity 174 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 559.97 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 manufactures Baloxavir Marboxil Impurity 174 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.
