Chemical Structure

Flupentixol Impurity 7 (E and Z Mixture) CAS 756419-50-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 434.52 g/mol gives Flupentixol Impurity 7 (E and Z Mixture) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Flupentixol Impurity 7 (E and Z Mixture) (CAS 756419-50-8), a pharmacopoeial impurity reference standard (molecular formula C23H25F3N2OS, MW 434.52 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, Flupentixol Impurity 7 (E and Z Mixture) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 434.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
