Used in pharmaceutical synthesis as an intermediate for bioactive compounds, particularly in the development of kinase inhibitors and antimicrobial agents. Its nitrile group allows for functional group transformations, enabling the creation of amides, amines, and heterocyclic derivatives. Employed in research settings to construct nitrogen-containing fused ring systems with potential neurological and oncological activity. Also applied in the design of fluorescent probes due to its aromatic structure and electron-withdrawing properties.
