Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive and antiviral agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing nitrogen-containing heterocyclic compounds. Commonly employed in cross-coupling reactions to introduce pyrazine moieties into target molecules, enhancing biological activity and metabolic stability. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and selectivity.
