Description

2,3,4,6-Tetra-o-Benzylgalactopyranosyl Phenyl Sulfoxide is a sophisticated, protected glycosyl donor, a key intermediate in the synthesis of complex oligosaccharides and glycoconjugates. Its value lies in its role as a critical building block for the stereoselective construction of galactose-containing structures, which are fundamental to research in glycobiology and pharmaceutical development. This high-purity intermediate is essential for scientists and manufacturers in the fields of carbohydrate chemistry, medicinal chemistry, and process development for novel therapeutics and diagnostic agents.

Application

• Glycosylation Reactions: A pivotal donor for the stereoselective synthesis of galactosides and oligosaccharides.
• Pharmaceutical Intermediate: Used in the research and development of glycoprotein-based drugs, vaccines, and antibody-drug conjugates (ADCs).
• Glycoconjugate Synthesis: Building block for creating complex glycoconjugates for biological studies and diagnostic tools.
• Carbohydrate Chemistry Research: A standard reagent in academic and industrial labs for developing new glycosylation methodologies.
• Process Chemistry: Serves as a key starting material in the scaled-up production of carbohydrate-active pharmaceutical ingredients (APIs).
• Glycomimetics Development: Used to synthesize sugar analogs for probing biological pathways and drug discovery.
