Used primarily as an intermediate in organic synthesis, especially in the development of pharmaceuticals and agrochemicals. Its structure allows for selective introduction of fluorinated vinyl groups, which can enhance metabolic stability and bioavailability in active compounds. Commonly employed in cross-coupling reactions and sulfonate displacement reactions to form carbon-carbon or carbon-heteroatom bonds. Valuable in the preparation of fluorinated analogs in medicinal chemistry due to the unique electronic and steric properties imparted by the difluoroethenyl group.
