Description

Methyl-6-o-(Tert.-Butyldiphenylsilyl)-2,3,4-Tri-o-Acetyl-α-D-Galactopyranoside CAS NO 169686-81-1 is a sophisticated, protected monosaccharide derivative, a crucial building block in synthetic carbohydrate chemistry. This compound matters because it provides a strategically protected galactose scaffold, enabling precise and selective glycosylation reactions in complex oligosaccharide synthesis. Pharmaceutical researchers and fine chemical manufacturers need it for the development of novel glycoconjugates, vaccines, and bioactive molecules where galactose motifs are essential.

Application

• Glycoscience Research: A key protected intermediate for the chemical synthesis of complex oligosaccharides and glycoconjugates.
• Pharmaceutical Development: Used in the synthesis of carbohydrate-based active pharmaceutical ingredients (APIs), prodrugs, and diagnostic agents.
• Glycobiology Probes: Serves as a precursor for labeled galactose derivatives used in metabolic pathway studies and biological assays.
• Glycopolymer Synthesis: A monomer for creating synthetic polymers with pendant galactose units for biomaterial and drug delivery applications.
• Enzyme Substrate Synthesis: Employed to prepare specific substrates for glycosidase and glycosyltransferase enzyme studies.
• Neoglycoconjugate Production: Facilitates the creation of artificial glycoproteins and glycolipids for immunological and therapeutic research.
