Used primarily as a fluorinating agent in organic synthesis, enabling the introduction of fluorine atoms into complex molecules. Its high reactivity makes it valuable in the development of fluorinated pharmaceuticals and agrochemicals, where fluorine substitution can enhance metabolic stability and bioavailability. Also investigated for use in specialty materials, including fluoropolymers and electronic chemicals, due to its ability to deliver fluorine under controlled conditions. Handles with care due to its moisture sensitivity and potential toxicity.
