Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the construction of heterocyclic compounds like pyrimidines and imidazoles. Its reactive cyano and ester groups enable efficient condensation reactions, making it valuable in forming carbon-nitrogen bonds. Commonly employed in the preparation of active ingredients in crop protection agents and in medicinal chemistry for developing kinase inhibitors and antiviral agents. Its hydrochloride salt form enhances stability and handling in industrial processes.
