Description

Acetamide, n-(Acetyloxy)-n-(2,3,4,6-Tetra-o-Acetyl-.Beta.-D-Galactopyranosyl)- is a key protected glycosyl donor intermediate in synthetic carbohydrate chemistry. This compound matters for its role in the precise and efficient construction of complex oligosaccharides and glycoconjugates, enabling research and development in pharmaceuticals and diagnostics. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, biotechnology, and fine chemical industries for the synthesis of novel therapeutic agents, vaccines, and diagnostic tools.

Application

• Glycosylation Reagent: Serves as a crucial building block for the stereoselective synthesis of β-linked galactose-containing oligosaccharides.
• Pharmaceutical Intermediate: Used in the research and development of glycoprotein-based drugs, monoclonal antibodies, and other biologics.
• Carbohydrate Chemistry Research: A fundamental tool in academic and industrial laboratories for studying glycosylation mechanisms and developing new synthetic methodologies.
• Glycoconjugate Synthesis: Enables the creation of labeled probes, vaccines (e.g., conjugate vaccines), and diagnostic agents that target specific carbohydrate-protein interactions.
• Fine Chemical Production: Employed in the multi-step synthesis of complex, high-value specialty chemicals with specific biological activities.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized by advanced analytical techniques to confirm identity, purity, and anomeric configuration. Certificates of Analysis (COA) detailing purity (typically by HPLC/NMR), physical data, and chromatographic profiles are available upon request, supporting your quality assurance and regulatory documentation needs.

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); therefore, containers must be kept tightly sealed and consideration should be given to storage under an inert atmosphere for long-term preservation of quality. Keep away from incompatible materials.
