Used as an intermediate in organic synthesis, particularly in pharmaceutical and agrochemical industries. Its functional groups—bromine, nitrile, and ester—allow for selective transformations, enabling the construction of complex molecules. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions, where the bromine moiety acts as a reactive site for carbon-carbon bond formation. The nitrile group can be hydrolyzed to carboxylic acids or reduced to amines, expanding its utility in building bioactive compounds. Also serves as a building block in the synthesis of heterocyclic compounds and functionalized aromatic systems.
