Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization, making it valuable in constructing complex heterocyclic systems. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to build carbon-carbon bonds in drug discovery. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its reactivity and ability to introduce bromine and aldehyde functionalities in target molecules.
