Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its structure allows for the introduction of cyano and ester functional groups, making it valuable in constructing heterocyclic compounds such as pyridines, pyrroles, and pyrimidines. Commonly employed in multicomponent reactions to build complex molecules efficiently. Also utilized in the synthesis of dyes and functional materials due to its ability to undergo cyclization and nucleophilic addition reactions.
