Used as a high-performance intermediate in specialty polymers, particularly in the synthesis of heat-resistant and chemically stable polyimides. Its fluorinated structure enhances solubility in organic solvents and improves the dielectric properties of resulting materials, making it valuable in electronics and aerospace applications. Also employed in surface treatment agents to provide water and oil repellency due to strong hydrophobic and oleophobic characteristics. Suitable for advanced coatings and functional materials requiring durability under extreme conditions.
