This compound is primarily used in organic synthesis as a protected intermediate for the preparation of various biologically active molecules, particularly in pharmaceutical research. It serves as a building block in the synthesis of peptides and other complex organic compounds, where the tert-butyl carbamate (Boc) group acts as a protecting group for amines. The hydrochloride form enhances its stability and solubility, making it easier to handle in chemical reactions. Its application is crucial in the development of drugs targeting specific diseases, as it allows for controlled and efficient modification of molecular structures during the synthesis process.
