Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of agrochemicals and active pharmaceutical ingredients (APIs). Its structure allows for selective functionalization, making it valuable in creating complex molecules. Commonly employed in cross-coupling reactions such as Suzuki and Negishi couplings to form carbon-carbon bonds in drug discovery. Also utilized in the preparation of kinase inhibitors and other biologically active compounds. Its halogen atoms enable stepwise substitution, offering flexibility in synthetic routes.
