Description
As a certified reference material (CRM), Baloxavir Marboxil Impurity 217 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.
Baloxavir Marboxil Impurity 217 (CAS CATO-C4X-2108217) is a certified pharmaceutical impurity reference standard with the molecular formula C14H10F2O2S and a molecular weight of 280.29 g/mol.
Structurally, Baloxavir Marboxil Impurity 217 (C14H10F2O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 280.29 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
