Used primarily as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, this compound serves as a building block for fluorinated aromatic compounds. Its reactive aldehyde and bromo groups allow for selective functionalization, making it valuable in cross-coupling reactions such as Suzuki or Heck reactions. It is also employed in the development of liquid crystals and organic electronic materials due to the electron-withdrawing nature of the fluorine substituents, which helps modulate electronic properties. Additionally, it finds use in the preparation of specialty polymers and dyes where thermal and chemical stability are required.
