Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the preparation of hydrazide and hydrazine derivatives. It serves as a protecting group reagent in peptide chemistry, enabling selective reactions by shielding reactive functional groups during multi-step syntheses. Commonly applied in the development of protease inhibitors and other bioactive molecules where controlled activation and stability are required. Its structure allows for clean deprotection under mild conditions, making it valuable in medicinal chemistry and drug design.
