Used as a fluorinating agent in organic synthesis, particularly in the introduction of trifluoromethyl groups into pharmaceuticals and agrochemicals. It serves as a building block in the production of fluoropolymers and fluoroelastomers, enhancing thermal stability and chemical resistance. Also employed in surface treatments to impart water and oil repellency to textiles, paper, and coatings. Its reactivity makes it valuable in specialty chemical manufacturing where strong electron-withdrawing groups are needed.
