Chemical Structure
Description
The occurrence of Baloxavir Impurity 57 is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Baloxavir Impurity 57 (CAS 2496644-37-0) is a certified pharmaceutical impurity reference standard with the molecular formula C14H10F2OS and a molecular weight of 264.29 g/mol.
Baloxavir Impurity 57 (C14H10F2OS) 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).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Baloxavir Impurity 57 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.
