Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its aldehyde group allows for easy functionalization, enabling the formation of Schiff bases, imines, and other derivatives useful in drug development. Commonly employed in the synthesis of heterocyclic compounds due to the reactivity of the furan ring and the electron-withdrawing nitro group, which enhances electrophilicity. Also applied in materials science for constructing conjugated systems in organic electronics.
