Chemical Structure
Description
The occurrence of 1-(4-Fluoro-3-(trifluoromethyl)phenyl)ethanamine hydrochloride is closely related to a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(4-Fluoro-3-(trifluoromethyl)phenyl)ethanamine hydrochloride (CAS 1131739-78-0), molecular formula C9H9F4NHCl and molecular weight 243.63 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H9F4NHCl, 1-(4-Fluoro-3-(trifluoromethyl)phenyl)ethanamine hydrochloride contains a nitrile group, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 243.63 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
