Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of pyrazine-based active pharmaceutical ingredients (APIs). Its nitrile and chloro functional groups allow for further chemical modifications, making it valuable in constructing complex heterocyclic compounds. Commonly employed in medicinal chemistry for developing drugs with antiviral, antibacterial, or kinase inhibitory activity. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its reactive scaffold.
