Used as a key intermediate in the synthesis of complex glycoconjugates and carbohydrate-based vaccines. Its azide functionality allows for efficient conjugation via click chemistry, particularly in Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reactions. The protected diol groups provide stability during synthetic transformations and can be selectively deprotected to enable further chain elongation in oligosaccharide assembly. Commonly employed in the preparation of antigenic structures for immunological studies and in the development of synthetic carbohydrate antigens for diagnostic and therapeutic applications.
