Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 174.21 g/mol gives 3-(1,1-Difluoroethyl)benzenethiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(1,1-Difluoroethyl)benzenethiol (CAS 1896970-19-6), a certified reference material (molecular formula C8H8F2S, MW 174.21 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, fluorine substitution, an aromatic ring system, 3-(1,1-Difluoroethyl)benzenethiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.21 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
