This compound is primarily used in the synthesis of complex carbohydrates and glycoconjugates, serving as a key intermediate in the preparation of biologically active molecules. It plays a significant role in glycosylation reactions, where it acts as a protected glycosyl donor, enabling the selective formation of glycosidic bonds. Its acetyl and phthalimido groups provide stability and control during chemical transformations, making it valuable in the production of oligosaccharides and glycoproteins. Additionally, it is utilized in research focused on developing new therapeutic agents, particularly in the field of glycobiology, where understanding carbohydrate interactions is crucial for drug design and vaccine development.
