Used primarily as a fluorinated building block in organic synthesis, especially in the development of specialty fluorochemicals. Its terminal double bonds allow for further functionalization through reactions like metathesis, hydroformylation, or polymerization. Commonly employed in the preparation of fluorinated surfactants, polymers, and surface modifiers where enhanced thermal stability, chemical resistance, and unique surface properties are required. Also finds use in pharmaceutical and agrochemical research due to the influence of fluorine on bioavailability and metabolic stability.
