Used as a protected amine intermediate in organic synthesis, particularly in pharmaceutical and agrochemical manufacturing. Its alkyne functionality allows participation in click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), enabling efficient molecular assembly. The tert-butoxycarbonyl (Boc) group provides reversible protection of the amine, facilitating selective reactions in multi-step syntheses. Commonly employed in the development of bioactive compounds where controlled reactivity and stability are required.
