Thiophosphoryl fluoride is an inorganic molecular gas with formula P S F₃ containing phosphorus, sulfur and fluorine. It spontaneously ignites in air and burns with a cool flame. The discoverers were able to have flames around their hands without discomfort,^[5] and called it "probably one of the coldest flames known".^[5] The gas was discovered in 1888.^[5]

It is useless for chemical warfare as it burns immediately and is not toxic enough.^[6]
