Used as an intermediate in organic synthesis, particularly in the pharmaceutical industry for the protection of amino groups during peptide synthesis. Its primary application lies in the preparation of protected aniline derivatives, which are key building blocks in the development of active pharmaceutical ingredients (APIs). The tert-butyloxycarbonyl (Boc) group allows for selective protection of the amine functionality, enabling multi-step syntheses under mild conditions. It is also employed in the production of dyes, agrochemicals, and specialty polymers where controlled reactivity of the amine group is required. The compound’s stability and ease of deprotection make it valuable in combinatorial chemistry and drug discovery processes.
