Description

6-o-(2-O,3-O,4-O,6-o-Tetraacetyl-α-D-Galactopyranosyl)-D-Glucopyranose Tetraacetate is a highly pure, fully acetylated disaccharide derivative that serves as a critical protected intermediate in synthetic carbohydrate chemistry. Its value lies in providing a stable, reactive scaffold for the precise construction of complex oligosaccharides and glycoconjugates. This compound is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and diagnostic sectors who require high-fidelity building blocks for glycosylation reactions and the development of novel therapeutics, vaccines, and research tools.

Application

• Glycochemistry Research: A fundamental building block for the chemical and enzymatic synthesis of complex oligosaccharides, glycopeptides, and glycolipids.
• Pharmaceutical Intermediate: Used in the development and production of carbohydrate-based drugs, including antiviral agents, antibiotics, and anti-cancer therapeutics.
• Vaccine Development: Serves as a key precursor for synthesizing antigenic carbohydrate moieties used in conjugate vaccine formulations.
• Diagnostic Reagent Synthesis: Employed in creating labeled sugar derivatives and probes for biochemical assays and diagnostic kits.
• Enzymology Studies: Acts as a substrate or inhibitor for studying the activity and specificity of glycosyltransferases, glycosidases, and other carbohydrate-processing enzymes.
• Material Science: Potential monomer for creating novel bio-based polymers and functional surfaces with specific carbohydrate recognition properties.

Quality Control

Our 6-o-(2-O,3-O,4-O,6-o-Tetraacetyl-α-D-Galactopyranosyl)-D-Glucopyranose Tetraacetate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and specific optical rotation measurement, to ensure it meets the high standards required for advanced synthetic applications. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability, batch-to-batch consistency, and compliance with relevant research and cGMP guidelines for pharmaceutical 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 compound is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent hydrolysis of the acetyl groups. For long-term storage, consider desiccant or inert atmosphere conditions.
