Used as a building block in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its terminal alkyne and primary amine functional groups allow for participation in coupling reactions, such as click chemistry via CuAAC (copper-catalyzed azide-alkyne cycloaddition), making it valuable in drug discovery and bioconjugation. It is also employed in the synthesis of specialty polymers and functional materials where molecular diversity and reactivity are required.
