Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 264.20 g/mol gives Fezolinetant Impurity 24 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Fezolinetant Impurity 24 (CAS CATO-C4X-327024) is a certified pharmaceutical impurity reference standard with the molecular formula C11H11F3O4 and a molecular weight of 264.20 g/mol.
Based on its molecular formula C11H11F3O4, Fezolinetant Impurity 24 contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 264.20 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.
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.
