Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated drug candidates where the fluorine atoms enhance metabolic stability and bioavailability. Its aldehyde group allows for easy functionalization, making it valuable in constructing complex organic molecules. Commonly employed in the preparation of agrochemicals and specialty materials, especially in routes requiring selective fluorination to fine-tune electronic and steric properties. Also utilized in the manufacture of liquid crystals and functional polymers due to its rigid aromatic core and polarized substituents.
