Description
Flupentixol Impurity 6 (E and Z Mixture) (CAS CATO-C4X-18956) is a certified pharmaceutical impurity reference standard with the molecular formula C17H11F3S and a molecular weight of 304.33 g/mol.
The molecular framework of Flupentixol Impurity 6 (E and Z Mixture) (C17H11F3S) is characterized by sulfur-containing functionality, 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. 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.
