Description

Raffinose Undecaacetate is a fully acetylated derivative of the trisaccharide raffinose, characterized by the acetylation of all eleven hydroxyl groups. This chemical modification significantly enhances its lipophilicity and stability, making it a valuable intermediate and reference standard in advanced synthetic and analytical chemistry. It is primarily utilized by researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors for applications such as carbohydrate chemistry research, analytical method development, and the synthesis of complex glycoconjugates.

Application

• Carbohydrate Chemistry Research: Serves as a key protected intermediate for the synthesis of complex oligosaccharides and glycoconjugates.
• Analytical Reference Standard: Used as a high-purity standard in HPLC, LC-MS, and NMR for method validation and quantification of acetylated sugars.
• Pharmaceutical Intermediate: Acts as a building block in the development of novel therapeutic agents, including glycomimetics and prodrugs.
• Biochemical Studies: Employed in enzymatic studies to investigate the activity of esterases and deacetylases.
• Material Science: Potential monomer or modifier in the synthesis of specialized polymers with tailored properties.
• Glycobiology Tool: Useful as a probe or substrate in studies of carbohydrate-protein interactions and metabolic pathways.
