2,3,4,6-Tetra-O-benzyl-D-galactopyranose（Cat No.:R000445）is a protected carbohydrate derivative in which the hydroxyl groups at positions 2, 3, 4, and 6 of D-galactopyranose are benzylated. This compound is commonly used as an intermediate in the synthesis of complex oligosaccharides, glycopeptides, and other glycoconjugates. The benzyl groups provide protection during selective glycosylation reactions and can be removed under mild hydrogenolysis conditions. Its stability and solubility in organic solvents make it ideal for use in synthetic carbohydrate chemistry. Typically supplied as a white solid, it supports precise control in multistep glycosylation strategies.
