Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antitubercular and antiviral agents. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in the preparation of pyrazine-based drug candidates due to its ability to enhance bioavailability and binding affinity. Also utilized in research settings for the design of kinase inhibitors and other biologically active molecules.
