Description

β-D-Gal-[1->3]-β-D-Gal-1->Ome CAS NO 81131-46-6 is a defined disaccharide derivative, specifically a methyl glycoside of a β-(1→3)-linked galactobiose. This compound is a crucial intermediate and reference standard in carbohydrate chemistry and glycobiology research. It is primarily required by scientists and manufacturers in the pharmaceutical, diagnostic, and biotechnology sectors for the synthesis, analysis, and quality control of complex carbohydrates and glycoconjugates.

Application

• Glycobiology Research: Used as a well-defined substrate or standard for studying enzyme activities, such as galactosyltransferases and glycosidases.
• Pharmaceutical Development: Serves as a key building block (glycosyl acceptor/donor) in the chemical and enzymatic synthesis of oligosaccharides for drug discovery and vaccine development.
• Diagnostic Reagent Production: Employed in the manufacture of calibration standards and reagents for diagnostic kits targeting carbohydrate antigens or metabolic disorders.
• Analytical Reference Standard: Provides a high-purity standard for HPLC, LC-MS, and NMR analysis to identify and quantify related carbohydrates in complex mixtures.
• Enzyme Characterization: Acts as a specific substrate for the characterization of the specificity and kinetics of carbohydrate-active enzymes.
• Biomimetic Synthesis: Utilized in the synthesis of glycopolymers, neoglycoconjugates, and other biomimetic materials for biomedical applications.
