Description

n-Acetyl-D-Galactosamine is a vital amino sugar derivative and a key building block in glycobiology and biochemistry. This high-purity monosaccharide is essential for the synthesis of complex carbohydrates, glycoproteins, and glycolipids. It is a critical raw material for research institutions and manufacturers in the pharmaceutical, diagnostic, and nutraceutical industries developing advanced glycosylation products and carbohydrate-based therapeutics.

Application

• Glycoconjugate Synthesis: A fundamental precursor for the chemical and enzymatic synthesis of oligosaccharides, glycopeptides, and glycolipids.
• Pharmaceutical Intermediates: Used in the research and production of novel drug candidates, including antiviral agents, cancer therapeutics, and anti-inflammatory drugs.
• Diagnostic Reagents: Serves as a key component in the manufacture of diagnostic kits and assays for detecting specific antibodies or carbohydrate-binding proteins.
• Biochemical Research: Essential for studying glycosyltransferase enzymes, carbohydrate-protein interactions, and cell surface recognition processes.
• Nutraceutical Development: Investigated for use in dietary supplements aimed at supporting joint health and cartilage formation.
• Cell Culture Media: Used as a specialized additive in certain mammalian cell culture systems to influence glycosylation patterns of recombinant proteins.

Quality Control

Our n-Acetyl-D-Galactosamine is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, specific rotation, and residual solvent analysis, to ensure it meets the high standards required for research and production. Certificates of Analysis (COA) are provided with every shipment, detailing all specifications and test results. We can supply material compliant with various pharmacopeial standards upon request.

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). Keep the container tightly sealed in a dry environment to prevent absorption of moisture, which may affect stability and performance.
