Description
As a certified reference material (CRM), Baloxavir Marboxil Impurity 190 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 190 (CAS CATO-C4X-2108190) is a certified pharmaceutical impurity reference standard with the molecular formula C14H10F2OS and a molecular weight of 264.29 g/mol.
The molecular framework of Baloxavir Marboxil Impurity 190 (C14H10F2OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
