Used as a key intermediate in the synthesis of pharmaceuticals and biologically active compounds, particularly in the development of kinase inhibitors and antitumor agents. Its alkyne and amine functional groups allow for versatile reactivity, including click chemistry applications such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable in medicinal chemistry and bioconjugation. Also employed in the preparation of specialty polymers and functional materials where tailored molecular architecture is required. Its structural rigidity and bifunctionality support the design of novel heterocyclic systems and enzyme inhibitors.
