Description

4-o-Galactopyranosyl-3,6-Anhydrogalactose Dimethylacetal is a specialized carbohydrate derivative, specifically a dimethylacetal of a disaccharide composed of galactose and 3,6-anhydrogalactose units. This compound serves as a valuable intermediate and building block in advanced organic synthesis and carbohydrate chemistry research. It is primarily needed by pharmaceutical R&D teams, specialty chemical manufacturers, and academic research institutions focused on developing novel glycoconjugates, surfactants, or functional materials.

Application

• Pharmaceutical Intermediate: Key starting material for the synthesis of complex glycans, glycomimetics, and potential active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a substrate or inhibitor in enzymatic studies related to glycosidases and glycosyltransferases.
• Surfactant & Detergent Chemistry: Serves as a hydrophilic head group precursor for the development of novel, biodegradable non-ionic surfactants.
• Material Science: Building block for creating functional polymers, hydrogels, or coatings with specific biocompatibility or hydration properties.
• Food Science R&D: Potential intermediate for developing novel food-grade emulsifiers, stabilizers, or prebiotic compounds.
• Cosmetic Ingredient Synthesis: Used in the research and development of advanced moisturizing or texturizing agents.
• Analytical Standard: Serves as a high-purity reference standard for chromatographic analysis and method validation in quality control laboratories.
• Glycobiology Studies: Essential tool for probing carbohydrate-protein interactions and cell surface recognition processes.

Quality Control

Our 4-o-Galactopyranosyl-3,6-Anhydrogalactose Dimethylacetal is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and MS, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) detailing all specifications and test results are provided and available upon request. We can support development projects requiring compliance with ISO or cGMP guidelines for advanced intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent absorption of atmospheric moisture. For long-term storage, consider using desiccants.
