Used as an intermediate in the synthesis of various biologically active compounds, particularly in the development of pharmaceuticals with antimicrobial, antifungal, and antitubercular properties. It serves as a key building block in the preparation of heterocyclic compounds such as oxadiazoles, triazoles, and pyridazines, which are common scaffolds in medicinal chemistry. Its hydrazide functionality allows for condensation reactions to form hydrazones, enhancing its utility in drug design and discovery. Also employed in the synthesis of fluorescent probes and coordination compounds due to its ability to chelate metal ions, making it useful in analytical chemistry and materials science.
