Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of heterocyclic compounds with biological activity. Its aldehyde and furan functionalities allow for versatile reactivity, enabling condensation and cyclization reactions to form nitrogen- and oxygen-containing rings. Commonly employed in the preparation of fluorescent dyes and sensors due to its ability to chelate metal ions and participate in conjugated systems. Also explored in materials science for constructing organic ligands in catalysis and coordination chemistry.
