Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and targeted cancer therapies. Its hydrazine and boronic acid functional groups enable conjugation in Suzuki-Miyaura cross-coupling reactions and facilitate the formation of hydrazone linkages, making it valuable in medicinal chemistry for building bioactive molecules. Commonly employed in the preparation of enzyme inhibitors where boron-containing structures enhance binding affinity to active sites. Also utilized in the design of prodrugs and biologically active probes due to its selective reactivity and stability under physiological conditions.
