Baloxavir Impurity 56 CAS CATO-C4X-210856

Description

The occurrence of Baloxavir Impurity 56 is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Baloxavir Impurity 56 (CAS CATO-C4X-210856), a pharmacopoeial impurity reference standard (molecular formula C25H21F2N3O6S2, MW 561.58 g/mol) used for the identification and quantification of trace impurities in APIs.

Baloxavir Impurity 56 (C25H21F2N3O6S2) contains a flavonoid 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.

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.

As a certified reference material (CRM), Baloxavir Impurity 56 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.
