Used extensively in carbohydrate chemistry as a glycosyl donor for the synthesis of complex oligosaccharides and glycoconjugates. It serves as a key intermediate in the preparation of biologically active molecules, particularly in the development of glycoproteins and glycolipids. Its benzyl-protected galactose moiety allows for selective deprotection and further functionalization, making it valuable in the study of glycosylation processes and the creation of glycomimetics. Additionally, it is employed in the design of glycosidase inhibitors and probes for investigating carbohydrate-protein interactions. Its stability and reactivity make it a versatile tool in medicinal chemistry and glycobiology research.
