Fluoromethanethiol

CAS: 70017-37-7

Category: Organic Intermediates

PurityResearch Grade ≥95%, High-Purity Grade ≥98%, Reagent Grade ≥99%
Molecular FormulaCH3FS
Molecular Weight68.10
AppearanceColorless to pale yellow volatile liquid or gas with a strong sulfurous odor (mercaptan odor).
PackagingSupplied in sealed glass ampoules, stainless steel cylinders, or pressure-resistant containers under inert gas protection.
Testing IndicatorsAppearance — Visual inspection; Identification — GC-MS and FTIR spectroscopy; Purity — Gas chromatography with flame ionization detection (GC-FID); Molecular structure confirmation — NMR (¹H NMR, ¹⁹F NMR); Water content — Karl Fischer titration; Sulfur content — Elemental analysis or ICP-OES; Residual impurities — GC-MS analysis.
Storage NotesStore in a cool, dry, well-ventilated area away from heat, sparks, flames, and oxidizing agents. Keep container tightly closed under inert atmosphere (nitrogen or argon). Due to its volatility and strong odor, handle only in a properly ventilated chemical fume hood. Avoid exposure to moisture and air for prolonged periods.
Lead Time10 days
Fluoromethanethiol is a sulfur-containing organic intermediate used mainly in specialty chemical synthesis, including the preparation of fluorinated thio-compounds, pharmaceutical intermediates, agrochemical intermediates, and materials chemistry research. It is also used as a research reagent for introducing fluoromethylthio (-SCH2F) functional groups.
