Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Its nitrile group allows for functional group transformations, enabling the preparation of amines, carboxylic acids, and heterocyclic compounds. Commonly employed in the development of bioactive molecules due to the cinnoline scaffold’s presence in compounds with antimicrobial, anti-inflammatory, and anticancer properties. Also utilized in materials science for constructing nitrogen-rich aromatic systems in functional dyes and electronic materials.
