1-[3-(Trifluoromethyl)phenyl]-2-butanone CAS 945226-71-1

Description

Compared with other compounds in its class, the molecular weight of 216.20 g/mol gives 1-[3-(Trifluoromethyl)phenyl]-2-butanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-[3-(Trifluoromethyl)phenyl]-2-butanone (CAS 945226-71-1) is a high-purity analytical reference standard with the molecular formula C11H11F3O and a molecular weight of 216.20 g/mol.

Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 1-[3-(Trifluoromethyl)phenyl]-2-butanone is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 216.20 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 is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
