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.
