Used primarily in the synthesis of glycosaminoglycans and other complex carbohydrates, this compound serves as a key intermediate in the production of heparin analogs and related polysaccharides. It is also employed in the preparation of modified sugars for biochemical research, particularly in studies involving carbohydrate-protein interactions. Additionally, it finds application in the development of glycoconjugate vaccines, where it aids in the creation of antigenic structures to enhance immune response. Its acetylated form provides stability during chemical reactions, making it suitable for controlled glycosylation processes in organic synthesis.
