Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the production of fine chemicals due to its reactive cyano and ester functional groups. Commonly employed in the synthesis of heterocyclic compounds, including pyridines and pyrimidines, which are core structures in many bioactive molecules. Also utilized in the development of dyes and specialty polymers. Its α,β-unsaturated structure allows participation in Michael addition reactions, making it valuable in constructing carbon-carbon bonds.
