Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals due to its reactive functional groups, including the aldehyde and hydroxy moieties. Its bromine atoms facilitate coupling reactions, such as Suzuki or Heck couplings, making it valuable in creating complex organic molecules. Also employed in the development of flame retardants because of the high bromine content, which helps suppress combustion through radical scavenging. Additionally, it serves as a building block in the preparation of dyes, pigments, and functional materials where halogenated aromatic structures are required, leveraging its electron-withdrawing properties.
