Used in organic synthesis as a building block for more complex molecules. Commonly employed in click chemistry reactions, particularly in the formation of triazoles via copper-catalyzed azide-alkyne cycloaddition. It serves as a precursor in the production of pharmaceuticals and bioactive compounds. Also utilized in material science for the modification of polymers and surfaces to introduce alkyne functional groups. Its reactive alkyne moiety makes it valuable in bioconjugation techniques for labeling biomolecules.
