Used as an intermediate in organic synthesis, particularly in the pharmaceutical industry for constructing complex molecules. It serves as a protected amine derivative, enabling selective reactions in multi-step syntheses. The tert-butyl carbamate group stabilizes the amine functionality under various reaction conditions and can be easily deprotected under mild acidic conditions, making it valuable in peptide synthesis and drug development. Its hydroxyl group allows for further functionalization, such as esterification or ether formation, expanding its utility in creating bioactive compounds.
