Chemical Structure
Description
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.
1-[(2-chloroethyl)sulfanyl]-3-(trifluoromethyl)benzene (CAS 448967-32-6) is a high-purity analytical reference standard with the molecular formula C9H8ClF3S and a molecular weight of 240.67 g/mol.
Owing to sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system, 1-[(2-chloroethyl)sulfanyl]-3-(trifluoromethyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.67 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).
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.
