Description

4-o-(2-O,3-O,4-O,6-o-Tetramethyl-β-D-Glucopyranosyl)-1-O,2-O,3-O,6-o-Tetramethyl-β-D-Glucopyranose is a highly pure, fully methylated disaccharide derivative, serving as a critical intermediate and reference standard in advanced chemical synthesis and analytical research. Its precisely defined structure makes it invaluable for studying carbohydrate chemistry, glycosylation mechanisms, and as a building block for complex oligosaccharides. This compound is essential for pharmaceutical R&D, academic laboratories, and specialty chemical manufacturers requiring high-purity, well-characterized carbohydrate precursors.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of complex carbohydrate-based drugs, prodrugs, and diagnostic agents.
• Analytical Reference Standard: Used in HPLC, GC, and NMR for method development, calibration, and quality control of related carbohydrate products.
• Glycoscience Research: A vital tool for studying enzymatic glycosylation, carbohydrate-protein interactions, and metabolic pathways in academic and industrial R&D.
• Chemical Synthesis: Acts as a protected glycosyl donor or acceptor in the stereoselective synthesis of oligosaccharides and glycoconjugates.
• Biochemical Reagent: Employed in enzymatic assays and as a substrate or inhibitor for glycosidases and glycosyltransferases.
• Material Science: Potential precursor for developing specialty surfactants, chiral selectors, or advanced polymeric materials with specific functionalities.
