Used as a protected amine intermediate in organic synthesis, particularly in pharmaceutical and agrochemical manufacturing. The tert-butyl carbamate group provides stability during reaction sequences and can be selectively removed under mild acidic conditions to release the free amine. The propargyl (prop-2-yn-1-yl) moiety allows for further functionalization via click chemistry, especially in coupling reactions like Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable in drug discovery and bioconjugation processes. Its structure supports modular assembly of complex molecules, including active pharmaceutical ingredients (APIs) and research compounds.
