Used primarily as a key intermediate in the production of epoxy resins, especially those requiring high thermal and chemical resistance. It is essential in synthesizing reactive diluents and resin modifiers that reduce viscosity while maintaining performance in coatings, adhesives, and composite materials. Due to its fluorinated structure, it imparts improved resistance to solvents, heat, and weathering in cured resin systems. Also employed in specialty polymers and fluorochemicals where enhanced stability and inertness are required. Its reactivity allows for functionalization in pharmaceutical and agrochemical synthesis, though such uses are limited due to handling challenges.
