Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of local anesthetics and anti-inflammatory drugs. Commonly employed in organic synthesis for the preparation of dyes, fragrances, and agrochemicals due to its reactive aldehyde and bromo functional groups. Serves as a building block in the manufacture of liquid crystals and in the development of certain photographic chemicals. Its bromine atom allows for coupling reactions, making it valuable in the construction of more complex aromatic compounds through metal-catalyzed reactions like Suzuki or Heck couplings.
