Used as a key intermediate in the synthesis of complex carbohydrates and glycosides, particularly in the development of biologically active compounds. Its protected sugar structure makes it valuable in stereoselective glycosylation reactions, enabling the construction of oligosaccharides for pharmaceutical and biochemical research. Commonly employed in the preparation of galactose-containing natural products and analogs for studying enzyme substrates or inhibitors. Also utilized in the design of prodrugs and glycoconjugate vaccines where precise sugar configuration is critical.
