Used as a key intermediate in click chemistry, particularly in copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions, enabling efficient synthesis of triazole-linked compounds for pharmaceuticals, agrochemicals, and bioconjugation. Its alkyne and triazole groups facilitate modular assembly of complex molecules, making it valuable in drug discovery, polymer science, and development of fluorescent probes or sensors. Also employed in materials science to functionalize surfaces and construct supramolecular architectures.
