Sulfuryl fluoride was first reported by M. Trautz and K. Ehrmann in 1935. It is relatively unreactive for a sulfur–fluorine compound, but it is very irritating to the respiratory tract. It is primarily used as a fumigant, especially for ridding structures of termites. SO2F2 is 4,000 times more powerful as a greenhouse gas than CO2, and it was recently shown that its persistence in the atmosphere is much longer than previously suspected.

Sulfuryl fluoride1 (SO2F2) is a relatively unreactive gas that is commonly used as a fumigant for controlling termites. It is also a greenhouse gas 4800 times more potent than CO2 with high atmospheric persistence. In October, two environmental organizations filed a legal petition with the California Air Resources Board to phase out fumigants that contain SO2F2 because of the chemical’s strong ability to trap heat in the atmosphere.
