Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antitubercular drugs like pyrazinamide. It plays a key role in medicinal chemistry due to its structural similarity to pyrazine derivatives, which exhibit biological activity against Mycobacterium tuberculosis. Also employed in the development of enzyme inhibitors and in research for designing new heterocyclic compounds with potential therapeutic applications. Its functional groups allow for derivatization in drug discovery programs.
