Used in carbohydrate chemistry as a key building block for the synthesis of complex oligosaccharides and glycoconjugates. It serves as a protected form of glucuronic acid, enabling controlled glycosylation reactions where the acetyl groups act as temporary protecting groups that can be selectively removed. Commonly employed in the preparation of biologically active molecules such as glycosaminoglycan fragments, drug metabolites, and vaccine components. Its methyl ester functionality stabilizes the molecule during synthesis while allowing further modification at the carboxyl group when needed. Widely applied in pharmaceutical research and development of carbohydrate-based therapeutics.
