Description

2,3,4,6-Tetra-o-Acetyl-β-D-Galactose Ethylxanthat is a key protected monosaccharide derivative, specifically an ethyl xanthate of peracetylated galactose, widely used as a versatile glycosylation donor and synthetic intermediate. Its primary value lies in enabling the stereoselective construction of complex oligosaccharides and glycoconjugates, which are critical for pharmaceutical and biochemical research. This high-purity building block is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors developing novel therapeutics, diagnostic tools, and advanced materials.

Application

• Glycosylation Reactions: Acts as a crucial glycosyl donor in the synthesis of oligosaccharides and glycoconjugates with controlled stereochemistry.
• Pharmaceutical Intermediates: Serves as a key building block in the research and development of novel active pharmaceutical ingredients (APIs), particularly in antiviral, anticancer, and anti-inflammatory drug candidates.
• Carbohydrate Chemistry Research: Used in academic and industrial laboratories for studying glycosylation mechanisms and developing new synthetic methodologies.
• Glycobiology Probes: Employed in the synthesis of labeled or modified sugars for use as probes in studying biological recognition and signaling pathways.
• Fine Chemical Synthesis: A valuable intermediate for creating specialty chemicals, chiral auxiliaries, and complex natural product analogs.

Quality Control

Our 2,3,4,6-Tetra-o-Acetyl-β-D-Galactose Ethylxanthat is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for research and synthesis. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by NMR and IR spectroscopy. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory needs.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
