Description

Ethyl 3,4,6-Tri-o-Benzyl-1-Thio-β-D-Galactopyranoside is a sophisticated, protected thioglycoside building block of significant importance in synthetic carbohydrate chemistry. Its core value lies in its role as a key glycosyl donor for the stereoselective construction of complex oligosaccharides and glycoconjugates. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical and biotechnology sectors, particularly those developing novel therapeutics, vaccines, and diagnostic tools that target carbohydrate-mediated biological processes.

Application

• Glycosylation Reagent: Serves as a crucial glycosyl donor in the synthesis of complex oligosaccharides and glycans.
• Pharmaceutical Intermediate: Used in the research and development of carbohydrate-based drugs, including antibiotics, antivirals, and anticancer agents.
• Glycoconjugate Synthesis: A key building block for creating glycoproteins, glycolipids, and other biologically active glycoconjugates for therapeutic and diagnostic applications.
• Chemical Biology Probes: Employed in the synthesis of molecular probes to study carbohydrate-protein interactions and glycosylation pathways.
• Vaccine Development: Utilized in the preparation of synthetic carbohydrate antigens for conjugate vaccine candidates.
• Enzyme Substrate/Inhibitor Synthesis: Acts as a precursor for creating substrates or inhibitors for glycosidases and glycosyltransferases.

Quality Control

Our Ethyl 3,4,6-Tri-o-Benzyl-1-Thio-β-D-Galactopyranoside is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity, suitable for demanding research and scale-up applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to relevant industry standards, and specifications can be tailored to meet specific project requirements, including those for cGMP manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). This compound is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) when possible to prevent oxidation and hydrolysis. Keep the container tightly sealed after each use to minimize exposure to moisture and air.
