1,3,4,6-TETRA-O-ACETYL-ALPHA-D-GALACTOPYRANOSE

Description:
1,3,4,6-Tetra-O-acetyl-alpha-D-galactopyranose is a derivative of galactose, a monosaccharide sugar. This compound features four acetyl groups attached to the hydroxyl groups of the galactopyranose ring, which enhances its stability and solubility in organic solvents. It is typically a white to off-white crystalline solid, exhibiting a sweet taste characteristic of sugars. The acetylation modifies its reactivity, making it less polar compared to the parent sugar, which can influence its behavior in various chemical reactions and applications. This compound is often used in organic synthesis, particularly in glycosylation reactions, due to its ability to act as a glycosyl donor. Additionally, it may serve as an intermediate in the synthesis of more complex carbohydrates or glycosides. Its CAS number, 19186-40-4, allows for easy identification in chemical databases. As with many acetylated sugars, it is important to handle this compound with care, as it may undergo hydrolysis in the presence of moisture, reverting to the parent sugar.
