Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the production of active ingredients that require brominated aromatic structures. It serves in the development of certain antifungal and antibacterial agents due to its reactivity in coupling reactions. Also employed in the preparation of dyes and fluorescent compounds, where the aldehyde and bromine groups allow for further functionalization. Its role in organic synthesis includes use in Horner-Wadsworth-Emmons and Suzuki coupling reactions to build complex molecules.
