Used in the synthesis of pharmaceuticals and agrochemicals, particularly as an intermediate in the production of pyrimidine-based compounds. It plays a key role in the development of certain antiviral and anticancer agents due to its reactive nitrile group and heterocyclic structure. Also employed in the manufacture of dyes and functional materials where nitrogen-rich rings enhance electronic properties. Its versatility in cross-coupling reactions makes it valuable in medicinal chemistry and materials science.
