Used as a key intermediate in the synthesis of biologically active quinoxaline derivatives, particularly in pharmaceuticals targeting antimicrobial, antiviral, and anticancer agents. Its hydrazine and thione functional groups enable cyclization and condensation reactions to form fused heterocyclic compounds with enhanced pharmacological properties. Also employed in coordination chemistry as a ligand for transition metal complexes, showing potential in catalysis and material science. Additionally, it serves in the development of organic sensors due to its ability to chelate metal ions and undergo detectable color changes.
