Used primarily as a key intermediate in the synthesis of fluorinated pharmaceuticals and agrochemicals. Its reactive double bond and carboxylic acid group allow for easy functionalization, making it valuable in building complex molecules with enhanced metabolic stability and bioavailability. Commonly employed in the preparation of fluorinated polymers and specialty monomers, where the fluorine atom imparts improved thermal and chemical resistance. Also utilized in research for developing novel enzyme inhibitors due to the electronegativity and small size of fluorine, which can mimic biological transition states.
