Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active ingredients for cardiovascular and central nervous system drugs. Its functional groups allow for selective reactions, making it valuable in constructing complex organic molecules. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to form carbon-carbon bonds in drug discovery. Also utilized in the preparation of agrochemicals and fine chemicals where brominated aromatic aldehydes serve as building blocks for further derivatization.
