Description

Galactose, Diethyl Mercaptal, Pentaacetate, D- is a high-purity, protected monosaccharide derivative, serving as a crucial chiral building block and synthetic intermediate. Its value lies in providing a chemically stable form of D-galactose, where the reactive hydroxyl and aldehyde groups are masked, enabling selective deprotection for complex carbohydrate synthesis. This compound is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors, particularly for developing glycoconjugates, glycomimetics, and advanced diagnostic reagents.

Application

• Pharmaceutical Intermediate: Key starting material for the synthesis of novel glycosidase inhibitors, antiviral agents, and complex glycan structures used in drug discovery.
• Glycobiology Research: Essential building block for the chemoenzymatic synthesis of oligosaccharides, glycopeptides, and glycolipids to study carbohydrate-protein interactions.
• Diagnostic Reagent Production: Used in the manufacture of substrates and probes for enzymatic assays and diagnostic kits targeting galactose-metabolizing enzymes.
• Fine Chemical Synthesis: Acts as a chiral precursor for the production of specialty chemicals, flavors, and fragrances requiring specific stereochemistry.
• Bioconjugation: Facilitates the site-specific labeling of proteins, antibodies, and nanoparticles with galactose moieties for targeted delivery and imaging.
• Academic & Industrial R&D: Serves as a standard and reagent in method development for carbohydrate chemistry and analytical studies.
