Used as a key intermediate in organic synthesis, particularly in click chemistry reactions due to the presence of the azide group. It enables the preparation of heterocyclic compounds and bioconjugates through copper-catalyzed azide-alkyne cycloaddition (CuAAC). Commonly employed in pharmaceutical research for developing amine-containing drug candidates and functionalized polymers. Also applied in bioconjugation techniques for labeling biomolecules, where the primary amine and azide groups allow dual functionalization. Its hydrochloride salt form enhances solubility and stability in aqueous reaction media.
