Used as a key intermediate in the synthesis of heterocyclic compounds, particularly in the preparation of pyridine and pyrrole derivatives. Its conjugated diene structure with an ester and amino group enables participation in cycloaddition and condensation reactions, making it valuable in pharmaceutical and agrochemical research. Commonly employed in the development of bioactive molecules, including potential antitumor and antimicrobial agents. Also applied in materials science for constructing conjugated organic systems used in dyes and fluorescent probes.
