Cas no 6291-42-5 (Lactose Octaacetate)

Lactose Octaacetate is a fully acetylated derivative of lactose, characterized by the substitution of all eight hydroxyl groups with acetyl moieties. This white, crystalline solid exhibits high chemical stability and low hygroscopicity, making it suitable for applications requiring moisture resistance. Its non-reducing nature and inertness under various conditions render it valuable as a protecting group in carbohydrate chemistry or as an intermediate in organic synthesis. The compound’s defined structure and purity allow for precise reproducibility in research and industrial processes. Additionally, its solubility in organic solvents, such as chloroform or acetone, facilitates its use in coatings, plasticizers, or specialty chemical formulations.
