Used as an intermediate in organic synthesis, particularly in the pharmaceutical industry for constructing complex molecules. Its hydroxyl and carbamate functional groups allow for selective modifications, making it valuable in the development of active pharmaceutical ingredients (APIs). Commonly employed in the protection of amines during multi-step syntheses due to the stability and ease of removal of the tert-butoxycarbonyl (Boc) group. Also utilized in the preparation of polymers and functionalized solvents where controlled reactivity and solubility are required.
