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.
