Used as a key intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds. It participates in cyclization reactions to form pyrimidines and other nitrogen-containing rings, which are common structures in pharmaceuticals and agrochemicals. Its reactivity makes it valuable in the synthesis of active pharmaceutical ingredients (APIs), especially in the development of antiviral and anticancer agents. Also employed in the production of specialty chemicals where nitrile and ester functionalities are required for further transformation.
