Used as a key intermediate in the synthesis of biologically active compounds, particularly in the development of sulfonamide-based pharmaceuticals. It serves as a hydrazide scaffold in the design of enzyme inhibitors, showing potential in antimicrobial and antitumor research. Its pyridine and tosylhydrazone moieties enable coordination with metal ions, making it useful in the preparation of metal-organic complexes for catalytic or medicinal applications. Also employed in the study of hydrazone-based Schiff bases due to its ability to form stable imine bonds, which are relevant in drug discovery and materials science.
