Sofosbuvir Impurity 46 CAS 874638-80-9

Description

Compared with other compounds in its class, the molecular weight of 372.34 g/mol gives Sofosbuvir Impurity 46 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Sofosbuvir Impurity 46 (CAS 874638-80-9) is a certified pharmaceutical impurity reference standard with the molecular formula C20H17FO6 and a molecular weight of 372.34 g/mol.

Based on its molecular formula C20H17FO6, Sofosbuvir Impurity 46 contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 372.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Sofosbuvir Impurity 46 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.
