Used as an intermediate in organic synthesis, particularly in the preparation of functionalized nitriles and heterocyclic compounds. It participates in cyclization reactions to form pyridine and pyrrole derivatives, which are important in pharmaceuticals and agrochemicals. Also employed in the development of fluorescent dyes and optoelectronic materials due to its conjugated structure and electron-withdrawing properties. Its reactivity makes it suitable for Knoevenagel condensations and Michael additions in the synthesis of complex organic molecules.
