Description

Abequose CAS NO 644-48-4 is a specialized monosaccharide derivative, specifically a 3,6-dideoxy-D-galactose, that serves as a critical building block in advanced biochemical research and synthesis. This compound is of significant interest for its role as a component of bacterial lipopolysaccharides (LPS) and O-antigens, making it a valuable tool for immunological and glycobiology studies. It is primarily utilized by researchers and manufacturers in the pharmaceutical, biotechnology, and life science sectors for the development of vaccines, diagnostic reagents, and novel glycoconjugates.

Application

• Glycobiology Research: A key precursor for synthesizing complex oligosaccharides and glycoconjugates to study carbohydrate-protein interactions.
• Vaccine Development: Used in the research and production of synthetic carbohydrate-based vaccines targeting specific bacterial pathogens.
• Diagnostic Reagents: Serves as a hapten or antigen in the development of immunoassays and diagnostic kits for bacterial detection.
• Enzyme Substrate Studies: Employed as a substrate to investigate the activity and specificity of glycosyltransferases and other carbohydrate-active enzymes.
• Chemical Synthesis: Acts as a chiral starting material or intermediate in the stereoselective synthesis of more complex natural products and pharmaceuticals.
• Microbial Immunology: Essential for studying the structure and immune response to bacterial cell wall components, particularly in Gram-negative bacteria.

Quality Control

Every batch of Abequose is produced and tested under a rigorous quality management system. We provide comprehensive analytical data to ensure identity, purity, and consistency for research and development purposes. A Certificate of Analysis (COA) detailing specifications such as purity (by HPLC), optical rotation, and moisture content is supplied with each shipment. Our quality protocols are designed to meet the exacting standards required for pharmaceutical and biochemical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept under anhydrous conditions. For long-term storage, consider storing under an inert atmosphere such as nitrogen or argon to maintain stability.
