Used as a key intermediate in glycochemistry for the synthesis of glycosylamines and modified carbohydrates through azide-based click chemistry. Its azido group allows for selective transformations via Staudinger reduction or copper-catalyzed azide-alkyne cycloaddition (CuAAC), enabling the development of glycoconjugates, neoglycoproteins, and carbohydrate-based vaccines. Commonly employed in biochemical labeling and probe development due to its bioorthogonal reactivity. Also applied in the preparation of glycosidase inhibitors and glycomimetic drugs.
