Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where nitrile and heterocyclic functionalities are required. Its structure allows for further functionalization, making it valuable in creating complex molecules for drug discovery. Commonly employed in reactions such as reductions, nucleophilic additions, and cyclizations to build targeted bioactive compounds. Also utilized in the preparation of agrochemicals and specialty chemicals due to its reactive nitrile group and stable ring system.
