Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive and antiviral agents. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building active pharmaceutical ingredients. Commonly employed in cross-coupling reactions to introduce pyrazine moieties into larger drug-like molecules. Also utilized in agrochemical research for the design of novel pesticides due to its electron-deficient aromatic core, which can enhance binding to biological targets.
