Used as a fluorinated aromatic diketone monomer and key intermediate in organic synthesis. It is primarily employed in the synthesis of high-performance fluorinated polymers such as polyether ether ketone (PEEK), polyimides, and polyetherketoneketone (PEKK), where the fluorine atoms lower the dielectric constant and improve thermal stability and hydrophobicity. Also used as an intermediate for optoelectronic materials, and in pharmaceutical and agrochemical synthesis.
