Description

Galactopyranose, 2,3,4,6-Tetra-o-Methyl-, D- is a high-purity, fully methylated derivative of D-galactose, serving as a crucial reference standard and synthetic intermediate. Its defined structure and high chemical purity are essential for ensuring analytical accuracy and reproducibility in research and development. This compound is primarily needed by pharmaceutical researchers, analytical laboratories, and fine chemical manufacturers working in carbohydrate chemistry, glycoscience, and the development of novel therapeutics and diagnostics.

Application

• Analytical Reference Standard: Used for the identification, method development, and quantification of carbohydrates and their derivatives via HPLC, GC-MS, and NMR.
• Pharmaceutical Research: Serves as a key building block (glycosyl donor/acceptor) in the synthesis of complex oligosaccharides, glycoconjugates, and potential drug candidates.
• Glycobiology Studies: Employed as a substrate or inhibitor in enzymatic assays to study glycosyltransferase or glycosidase activity and function.
• Chemical Synthesis: Acts as a protected intermediate for the precise synthesis of more complex, selectively functionalized sugar molecules.
• Quality Control: Utilized as an internal standard to ensure the purity and consistency of carbohydrate-based products in manufacturing.
