Chemical Structure

Baloxavir Marboxil Impurity 161 CAS CATO-C4X-2108161 chemical structure

Description

The occurrence of Baloxavir Marboxil Impurity 161 is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Baloxavir Marboxil Impurity 161 (CAS CATO-C4X-2108161) is a certified pharmaceutical impurity reference standard with the molecular formula C14H8F2O3S and a molecular weight of 294.27 g/mol.

Based on its molecular formula C14H8F2O3S, Baloxavir Marboxil Impurity 161 contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 294.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 manufactures Baloxavir Marboxil Impurity 161 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
