Used as a key intermediate in the synthesis of high-performance polymers, particularly in the production of fluorinated polyimides and polyamides. Its rigid, planar structure and electron-withdrawing fluorine atoms enhance thermal stability and improve the mechanical and dielectric properties of the resulting materials. Commonly applied in electronics and aerospace industries for manufacturing heat-resistant coatings, insulating films, and advanced composites. Also employed in research for developing organic semiconductors and optoelectronic devices due to its favorable electronic characteristics.
