Description

4-o-[3-o-(2-O,3-O,4-O,6-o-Tetramethyl-β-D-Galactopyranosyl)-2-O,4-O,6-o-Trimethyl-β-D-Galactopyranosyl]-1-O,2-O,3-O,5-O,6-o-Pentamethyl-D-Glucitol is a complex, fully methylated oligosaccharide derivative, specifically a trisaccharide of galactose and glucitol. This compound is valued for its role as a key intermediate and reference standard in advanced carbohydrate chemistry and analytical research. It is primarily needed by pharmaceutical R&D laboratories, academic research institutions, and specialty chemical manufacturers working on glycoscience, drug discovery, and the synthesis of complex biomolecules.

Application

• Pharmaceutical Research Intermediate: Serves as a crucial building block for the synthesis of complex glycoconjugates, glycomimetics, and novel drug candidates.
• Analytical Reference Standard: Used as a high-purity standard in chromatographic (HPLC, GC) and spectroscopic (NMR, MS) methods for method development, validation, and quality control of carbohydrate-based products.
• Glycobiology Studies: Employed in research to study enzyme specificity (glycosyltransferases/glycosidases), carbohydrate-protein interactions, and metabolic pathways.
• Chemical Synthesis: Acts as a protected synthon for the preparation of more complex oligosaccharides, glycodendrimers, and neoglycoconjugates.
• Process Development: Utilized in scaling up and optimizing synthetic routes for carbohydrate-based active pharmaceutical ingredients (APIs) or specialty chemicals.
