Cas no 138196-19-7 (a-D-Galactopyranose 1,2-(Methyl Orthoacetate))
a-D-Galactopyranose 1,2-(Methyl Orthoacetate) is a chemically protected derivative of galactose, featuring an orthoester group at the C1 and C2 positions. This modification enhances stability under acidic and basic conditions, making it a valuable intermediate in carbohydrate chemistry and glycosylation reactions. The orthoacetate group serves as a protective moiety, enabling selective deprotection for controlled synthetic applications. Its high purity and well-defined structure ensure reproducibility in oligosaccharide synthesis and glycoconjugate development. The compound is particularly useful in medicinal chemistry and glycobiology research, where precise glycosidic bond formation is critical. Its compatibility with standard glycosylation protocols further underscores its utility in complex synthetic pathways.
