Description

4-o-[4-o-(2-O,3-O,4-O,6-o-Tetramethyl-β-D-Galactopyranosyl)-2-O,3-O,6-o-Trimethyl-β-D-Galactopyranosyl]-1-O,2-O,3-O,5-O,6-o-Pentamethyl-D-Glucitol is a highly specific, fully methylated trisaccharide derivative. 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 R&D laboratories and manufacturers in the pharmaceutical and life science sectors for the synthesis and study of complex oligosaccharides.

Application

• Pharmaceutical Intermediate: Used in the synthesis of complex carbohydrate-based drugs, prodrugs, and glycoconjugates.
• Analytical Reference Standard: Serves as a high-purity standard for chromatographic (HPLC, GC) and spectroscopic (NMR, MS) analysis in quality control and method development.
• Glycobiology Research: A critical tool for studying enzyme mechanisms (e.g., glycosyltransferases, glycosidases), carbohydrate-protein interactions, and metabolic pathways.
• Chemical Synthesis Building Block: Employed as a protected synthon for the construction of larger, more complex oligosaccharide structures with precise stereochemistry.
• Process Development: Used in scaling up and optimizing synthetic routes for carbohydrate-active ingredients.
