Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 293.16 g/mol gives 3-(Trifluoroacetyl)-4-(trifluoromethyl)quinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(Trifluoroacetyl)-4-(trifluoromethyl)quinoline (CAS 155495-61-7) is a high-purity analytical reference standard with the molecular formula C12H5F6NO and a molecular weight of 293.16 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 3-(Trifluoroacetyl)-4-(trifluoromethyl)quinoline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 293.16 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.
