Chemical Structure

Baloxavir Marboxil Impurity 193 CAS 2591558-80-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 264.29 g/mol gives Baloxavir Marboxil Impurity 193 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Baloxavir Marboxil Impurity 193 (CAS 2591558-80-2) 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 193 (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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
