Description

1,3,4,6-Tetra-o-Acetyl-2-(2’,3’,4’-Tri-o-Benzoyl-α-L-Fucopyranosyl)-α-D-Galactopyranose CAS NO 56889-55-5 is a complex, fully protected disaccharide derivative, serving as a critical synthetic intermediate in advanced carbohydrate chemistry. Its value lies in providing a precisely functionalized scaffold for the controlled synthesis of oligosaccharides and glycoconjugates, which are essential for biological research and pharmaceutical development. This high-purity building block is primarily needed by research institutions and pharmaceutical companies engaged in glycobiology, vaccine development, and the synthesis of novel therapeutic agents.

Application

• Glycoconjugate Vaccine Synthesis: A key protected intermediate for constructing specific carbohydrate antigens used in conjugate vaccine development against bacterial pathogens.
• Oligosaccharide Assembly: Serves as a crucial building block in automated and solution-phase synthesis of complex, biologically active oligosaccharides.
• Pharmaceutical Intermediate: Used in the research and development of carbohydrate-based drugs, including selectin inhibitors and anti-inflammatory agents.
• Glycobiology Research: Essential for studying carbohydrate-protein interactions, enzyme mechanisms, and cell signaling pathways.
• Diagnostic Reagent Development: Employed in the creation of specific probes and standards for diagnostic assays targeting carbohydrate biomarkers.
• Chemical Biology Tool: Utilized to create labeled or modified sugars for tracking metabolic pathways or imaging studies.

Quality Control

Our production of this advanced synthetic intermediate adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for sensitive research applications. Each lot is characterized using advanced analytical techniques, including NMR (1H and 13C), HPLC, and mass spectrometry, to confirm identity, purity, and absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We support development under GMP-like conditions for pre-clinical and clinical-stage projects upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C in a dry, cool place. This compound is hygroscopic (moisture-sensitive); containers must be sealed under inert atmosphere (argon or nitrogen) after opening to prevent decomposition. Long-term storage is recommended at -20°C.
