Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of brominated aromatic compounds. It serves as a building block in organic reactions, including coupling reactions for the preparation of complex molecules. Its aldehyde and bromine functionalities allow for selective modifications, making it valuable in the creation of dyes, fragrances, and functional materials. Commonly employed in research settings for constructing heterocyclic compounds and in the design of bioactive molecules.
