Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive and antiviral agents. Its structure supports the formation of heterocyclic compounds that are active in biological systems. Commonly employed in medicinal chemistry for constructing pyrazine-based drug candidates. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its electron-deficient ring system, which enhances binding to target enzymes in pathogens or pests.
