β-D-Galactose pentaacetate

Description:

β-D-Galactose pentaacetate is an acetylated derivative of β-D-galactose, a monosaccharide. This compound is characterized by the presence of five acetyl groups attached to the hydroxyl groups of the galactose molecule, which enhances its lipophilicity and stability compared to the parent sugar. It typically appears as a white to off-white crystalline solid and is soluble in organic solvents such as chloroform and acetone, but less soluble in water due to the acetylation. The acetylation process modifies the reactivity of the hydroxyl groups, making β-D-galactose pentaacetate useful in various chemical applications, including as a protecting group in organic synthesis. Its molecular structure allows for specific interactions in biochemical assays and research, particularly in studies involving carbohydrate chemistry. Additionally, it can be utilized in the synthesis of glycosides and other derivatives, contributing to the understanding of carbohydrate functionality in biological systems. As with many acetylated compounds, it is important to handle β-D-galactose pentaacetate with care, following appropriate safety protocols.

1,2,3,4,6-Penta-O-acetyl-b-D-galactopyranose, also known as beta-D-galactose pentaacetate, has high chemical stability and long shelf life. This protected form of galactose is a key building block of any chemical synthesis of galactose-containing oligosaccharides or glycoconjugates. In the presence of Lewis acids it can be used as a glycosyl donor to make simple glycosides. In order to perform more complex galactosylations it can be converted into more reactive donors, such as glycosyl halides or thioglycosides.
