Used primarily as a building block in organic synthesis, especially in the development of pharmaceuticals and agrochemicals. Its amine and alkyne functional groups allow for versatile reactivity, including use in click chemistry reactions like copper-catalyzed azide-alkyne cycloaddition (CuAAC). This makes it valuable in drug discovery for constructing complex molecules and bioconjugation. It also serves in the synthesis of specialty polymers and functional materials where controlled molecular architecture is required.
