Chemical Structure

4-Trifluoromethyl thioanisole CAS 329-14-6 chemical structure

Description

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.

4-Trifluoromethyl thioanisole (CAS 329-14-6), molecular formula C8H7F3S and molecular weight 192.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, fluorine substitution, an aromatic ring system, 4-Trifluoromethyl thioanisole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
