  • Applications

    Chemical: alpha-D-Glucopyranoside, beta-D-fructofuranosyl, acetate 2-methylpropanoate (CAS 137204-24-1) is primarily used as a protected disaccharide building block in carbohydrate synthesis; it serves as an intermediate and as a glycosyl donor/acceptor for constructing oligosaccharides and for developing glycomimetics. In pharmaceutical and biotech research, it is used as a reference substrate in enzymatic and chemical glycosylation studies and as a chiral building block for asymmetric synthesis. It can also function as a protecting-group-laden substrate for protecting hydroxyl groups during complex syntheses, and is commonly evaluated as a precursor for glycosylated natural product analogs. Additionally, it may be used as an analytical standard or model substrate in carbohydrate analysis and method development.
