Product Description:

Β-D-Galactose pentaacetate is a fully acetylated derivative of D-galactose. It is a white to off-white crystalline solid with a molecular formula of C16H22O11 and a molecular weight of 390.34 g/mol. This compound is a common protected form of galactose, where all five hydroxyl groups are acetylated, making it stable and soluble in organic solvents. Its primary application is as a crucial intermediate in carbohydrate chemistry and glycobiology research. It serves as a protected building block for the chemical and enzymatic synthesis of oligosaccharides, glycoconjugates, and complex carbohydrates. These synthesized molecules are essential for studying biological recognition processes, developing glycan-based diagnostics, and exploring potential therapeutic agents. It is also used in the preparation of glycosides and other galactose-containing compounds. As a protected sugar derivative, it is a fundamental starting material in organic synthesis, particularly for constructing biologically active molecules that contain galactose moieties. Its stability and well-defined reactivity make it a standard reagent in laboratories focused on glycoscience.
