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 when needed. The presence of the propargyl ether moiety enables further derivatization via click chemistry, especially copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable in the development of compound libraries, bioconjugation, and drug discovery. Its polyether chain enhances solubility in polar solvents, facilitating use in solution-phase synthesis.
