Compared with other compounds in its class, the molecular weight of 208.20 g/mol gives 3-Methyl-4-((trifluoromethyl)thio)phenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Methyl-4-((trifluoromethyl)thio)phenol (CAS 774-71-0), a certified reference material (molecular formula C8H7F3OS, MW 208.20 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 3-Methyl-4-((trifluoromethyl)thio)phenol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
