Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 549.66 g/mol gives Baloxavir Impurity 20 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Baloxavir Impurity 20 (CAS CATO-C4X-210820) is a certified pharmaceutical impurity reference standard with the molecular formula C30H32FN3O4S and a molecular weight of 549.66 g/mol.
Baloxavir Impurity 20 (C30H32FN3O4S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), Baloxavir Impurity 20 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
