Chemical Structure

Atomoxetine EP Impurity F HCl CAS CATO-C4X-155013 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 309.81 g/mol gives Atomoxetine EP Impurity F HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Atomoxetine EP Impurity F HCl (CAS CATO-C4X-155013), a pharmacopoeial impurity reference standard (molecular formula C17H20FNOHCl, MW 309.81 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Atomoxetine EP Impurity F HCl (C17H20FNOHCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 309.81 g/mol, it falls into the moderately-high-molecular-weight range. 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.
