Description

D-Galactose, 2-(Acetylamino)-2-Deoxy-3,4,5,6-Tetrakis-o-(Trimethylsilyl)- is a key protected monosaccharide derivative, specifically a per-silylated N-acetylgalactosamine, designed for advanced synthetic chemistry. This compound is essential for researchers and manufacturers requiring a stable, non-reactive intermediate for the controlled synthesis of complex oligosaccharides, glycoconjugates, and bioactive molecules. It is primarily utilized in pharmaceutical R&D, carbohydrate chemistry, and the production of specialized biochemical reagents where precise glycosylation is critical.

Application

• Glycosylation Reagent: A crucial building block for the stereoselective synthesis of oligosaccharides and glycopeptides in medicinal chemistry.
• Pharmaceutical Intermediate: Used in the research and development of novel therapeutics, including antiviral drugs, cancer vaccines, and diagnostic agents.
• Carbohydrate Chemistry Research: Serves as a protected donor molecule in academic and industrial laboratories studying glycosylation mechanisms and enzyme specificity.
• Bioconjugation: Enables the site-specific attachment of carbohydrate motifs to proteins, lipids, or other carriers for creating targeted biopharmaceuticals.
• Standards and Reference Material: Used as a high-purity analytical standard in quality control and method development for glycobiology assays.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for research and synthesis. Every batch is characterized using advanced analytical techniques including NMR, HPLC, and mass spectrometry to confirm identity, purity, and stability. Certificates of Analysis (COA) are available upon request, providing full transparency on specifications. We adhere to cGMP principles where applicable to support our clients' regulatory needs in pharmaceutical development.

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); therefore, containers must be kept tightly sealed and may require storage under an inert atmosphere for long-term stability. Keep away from heat and open flame.
