Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) for drugs targeting central nervous system disorders and anti-inflammatory agents. Its structure allows for selective functionalization, making it valuable in creating complex organic molecules. Also employed in the development of agrochemicals, including herbicides and fungicides, due to its reactivity and stability in various chemical transformations. Additionally, it serves as a building block in the preparation of dyes, fluorescent probes, and specialty polymers where halogenated aromatic aldehydes are required.
