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 or Heck reactions to form carbon-carbon bonds in drug discovery. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its electron-withdrawing nitrile group and reactive bromine site.
