Used primarily as an intermediate in organic synthesis, especially in the preparation of hydrazine derivatives for pharmaceuticals. It serves as a protected hydrazine reagent in the development of bioactive molecules, including antitumor agents and enzyme inhibitors. Its tert-butyloxycarbonyl (Boc) protection allows for selective reactions in multi-step syntheses, making it valuable in medicinal chemistry for constructing nitrogen-containing heterocycles. Also applied in the synthesis of functionalized hydrazones, which are important in drug discovery and agrochemical research.
