Used as a building block in organic synthesis, particularly in pharmaceutical and agrochemical research. Its terminal alkyne group enables click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable for constructing complex molecules and bioconjugates. The amine functionality, protected as the hydrochloride salt, allows for selective derivatization and incorporation into larger molecular frameworks. Commonly employed in the development of functionalized polymers, probes, and intermediates for drug discovery.
