Used in organic synthesis as a fluorinated building block for pharmaceuticals and agrochemicals. Its alkyne functionality allows participation in click chemistry, particularly copper-catalyzed azide-alkyne cycloaddition (CuAAC), enabling efficient construction of heterocyclic compounds. Also employed in the development of fluorinated analogs in medicinal chemistry to enhance metabolic stability and bioavailability. Serves as an intermediate in synthesizing liquid crystals and functional materials where fluorine substitution influences electronic properties.
