Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) drugs and antidepressants. Its structure allows for selective derivatization, making it valuable in creating compounds with specific biological activity. Also employed in the preparation of agrochemicals and fine chemicals where fluorinated aromatic building blocks enhance metabolic stability and bioavailability. Commonly utilized in research and development settings for designing novel organic molecules due to its reactive aldehyde group and fluorinated aromatic ring.
