This chemical is primarily used in organic synthesis as a key intermediate for the preparation of complex carbohydrates and glycoconjugates. It is particularly valuable in glycosylation reactions, where it serves as a glycosyl donor to introduce galactose units into various molecules. This is crucial in the development of oligosaccharides, glycoproteins, and glycolipids, which have significant roles in biological processes and pharmaceutical research. Additionally, it is employed in the synthesis of glycosides and other sugar derivatives, which are important in drug discovery and the study of carbohydrate-protein interactions. Its acetyl groups provide stability and facilitate selective reactions, making it a versatile reagent in carbohydrate chemistry.
