Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antihypertensive and antiviral drugs. It serves as a building block in the development of pyrazine-based bioactive molecules due to its reactive nitrile group and methyl functionality, which allow for further chemical modifications. Commonly employed in medicinal chemistry for structure-activity relationship studies and in the design of heterocyclic compounds with potential therapeutic effects. Also utilized in the preparation of agrochemicals and functional materials where nitrogen-containing aromatic systems are required.
