Used as an intermediate in organic synthesis, particularly in the preparation of hydrazine derivatives for pharmaceuticals and agrochemicals. It serves as a protected hydrazine reagent, allowing selective reactions in multi-step syntheses. Commonly employed in the development of nitrogen-containing heterocycles, including pyrazoles and triazoles, which are key scaffolds in drug discovery. Also utilized in peptide coupling and as a building block in medicinal chemistry for constructing bioactive molecules.
