Used as a key intermediate in organic synthesis, particularly in the preparation of nitrogen-containing heterocyclic compounds. Its active methylene and cyano groups allow for cyclization reactions, making it valuable in constructing pyridines, pyrroles, and other fused ring systems. Commonly employed in pharmaceutical and agrochemical research for developing bioactive molecules. Also utilized in material science for synthesizing specialty polymers and functionalized organic frameworks due to its ability to undergo condensation and nucleophilic addition reactions.
