Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting central nervous system disorders. Its functional groups allow for selective modifications, making it valuable in creating active pharmaceutical ingredients (APIs) with specific biological activity. Also employed in the preparation of agrochemicals and fine chemicals where brominated aromatic aldehydes serve as building blocks for more complex molecules. The aldehyde group enables condensation reactions, while the bromine facilitates cross-coupling reactions, offering versatility in organic synthesis.
