Used as a protected amine building block in organic synthesis, particularly in pharmaceutical and agrochemical research. The tert-butyl carbamate (Boc) group provides stability under various reaction conditions while allowing selective deprotection to release the amine for further transformations. The propargyloxy aromatic moiety enables participation in click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable in the development of bioconjugates, drug discovery libraries, and functionalized molecules for materials science. Its bifunctional nature allows for sequential modification and coupling in multi-step syntheses.
