Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals. Its aldehyde functional group allows for easy modification into various derivatives, making it valuable in drug development. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) where a brominated aromatic backbone is required. Also utilized in the production of fragrances and flavoring agents due to its reactive structure that can be tailored to produce specific olfactory properties. Serves as a building block in organic synthesis, particularly in cross-coupling reactions and the formation of carbon-carbon bonds.
