Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of pyrimidine-based drugs. It plays an important role in the preparation of antiviral and anticancer agents due to its ability to participate in cyclization and nucleophilic addition reactions. Its nitrile and ester functional groups allow for versatile chemical modifications, making it valuable in medicinal chemistry for building complex heterocyclic systems. Also employed in agrochemical research for designing novel pesticides with improved efficacy and selectivity.
