Used as a key intermediate in organic synthesis, particularly in the preparation of functionalized alkenes and heterocyclic compounds. Its active methylene group allows for condensation reactions, making it valuable in constructing carbon-carbon double bonds in fine chemicals and pharmaceuticals. It is also employed in the synthesis of dyes and nonlinear optical materials due to its electron-withdrawing cyano groups and ability to form conjugated systems. Additionally, it serves as a building block in the development of specialty polymers and agrochemicals.
