Product Description
D-Galactopyranose pentaacetate, with CAS number 25878-60-8, is a fully acetylated derivative of galactose. It serves as a crucial and versatile building block in carbohydrate chemistry. As a protected form of galactose, it is widely utilized as a glycosyl donor or intermediate in the synthesis of more complex oligosaccharides, nucleosides, and various glycoconjugates. Its acetyl groups provide stability and allow for controlled, regioselective deprotection, making it an essential reagent in multi-step organic synthesis and pharmaceutical research.
