Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and other bioactive compounds. Its aldehyde and bromine functionalities allow for selective cross-coupling reactions and condensation, making it valuable in constructing heterocyclic systems for drug discovery. Also employed in agrochemicals for creating novel pesticides with improved efficacy and selectivity. Its reactivity supports use in research laboratories for building complex molecules through palladium-catalyzed couplings and nucleophilic substitutions.
