Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and antibacterial agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building complex heterocyclic compounds. Commonly employed in cross-coupling reactions to introduce pyrazine moieties into target molecules, enhancing their biological activity. Also utilized in agrochemical research for designing novel pesticides due to its reactivity and stability in various reaction conditions.
