Used as a key intermediate in organic synthesis, particularly in click chemistry reactions. Its azide group readily participates in copper-catalyzed azide-alkyne cycloaddition (CuAAC), forming stable triazole linkages, which are valuable in pharmaceutical development, bioconjugation, and polymer chemistry. The hydroxyl group allows for further functionalization, enabling attachment to various scaffolds or surfaces. Commonly employed in the preparation of drug candidates, fluorescent probes, and functionalized biomolecules for research and diagnostic applications.
