Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the preparation of heterocyclic compounds, particularly in the development of bioactive molecules and functional materials. Its aldehyde group allows for condensation reactions, enabling the formation of Schiff bases and other derivatives useful in medicinal chemistry. Also employed in the synthesis of conjugated systems for optoelectronic applications due to the electron-rich furan ring and bromine handle for cross-coupling reactions.
