Used primarily as a fluorinating agent in organic synthesis, enabling the introduction of fluorine atoms into various compounds. It is effective in transforming alcohols, carbonyls, and other functional groups through selective fluorination. Also serves as a source of fluoride ions in electrochemical applications and catalysis. Its strong oxidizing properties make it suitable for specialized reactions requiring high reactivity, particularly in the preparation of fluorinated pharmaceuticals and agrochemicals. Handle with care due to its moisture sensitivity and corrosive nature.
