Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules. Its functional groups—aldehyde, hydroxyl, and bromine—allow for selective chemical modifications, making it valuable in constructing complex organic compounds. Commonly employed in cross-coupling reactions due to the presence of bromine, enabling the formation of carbon-carbon bonds. Also utilized in the preparation of dyes and specialty aromatic compounds where controlled substitution patterns are required.
