Used as a key intermediate in the synthesis of pyrazine-based pharmaceuticals, particularly in the production of certain antihypertensive and antiviral agents. Its nitrile and chloro functional groups allow for selective transformations, enabling the construction of complex heterocyclic systems. Commonly employed in medicinal chemistry for derivatization to enhance biological activity or improve pharmacokinetic properties. Also utilized in agrochemical research for developing novel pesticides with improved efficacy and selectivity.
