Used as an intermediate in carbohydrate chemistry, particularly in the synthesis of complex oligosaccharides and glycoconjugates. Its acetylated groups provide protection during glycosylation reactions, allowing selective bond formation in the production of pharmaceuticals and biologically active molecules. Commonly employed in the development of vaccines and enzyme inhibitors where precise sugar structure is critical. Also serves as a building block in the preparation of modified sugars for use in prodrugs and drug delivery systems.
