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 240 (CAS CATO-C4X-2108240), a pharmacopoeial impurity reference standard (molecular formula C10H10N4O5, MW 266.21 g/mol) used for the identification and quantification of trace impurities in APIs.
Baloxavir Marboxil Impurity 240 (C10H10N4O5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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).
As a certified reference material (CRM), Baloxavir Marboxil Impurity 240 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.
