Used as a key intermediate in the synthesis of high-performance polymers, particularly in the production of fluorinated polyimides. These polyimides exhibit excellent thermal stability, low dielectric constants, and good solubility, making them suitable for advanced electronic applications such as insulating layers in microchips and flexible printed circuits. Also employed in the development of specialty resins and coatings where enhanced chemical resistance and thermal performance are required. Its fluorinated structure contributes to improved hydrophobicity and oxidative stability in the final materials. Additionally, it serves as a building block in the preparation of certain pharmaceuticals and fluorescent dyes due to its rigid aromatic framework and reactivity toward nucleophiles.
