Description

β-Gentiobiose Octaacetate is a fully acetylated derivative of the disaccharide gentiobiose, serving as a crucial protected intermediate in synthetic carbohydrate chemistry. This compound is valued for its stability and solubility in organic solvents, facilitating controlled glycosylation reactions and the synthesis of complex oligosaccharides. It is primarily required by research institutions and pharmaceutical companies engaged in the development of novel glycoconjugates, bioactive sugars, and advanced materials.

Application

• Chemical Synthesis Intermediate: Acts as a key protected building block for the controlled synthesis of gentiobiose-containing oligosaccharides and glycoconjugates.
• Glycobiology Research: Used as a standard or substrate in enzymatic studies to investigate glycosidase and glycosyltransferase activities.
• Pharmaceutical Development: Employed in the research and development of carbohydrate-based drugs, prodrugs, and diagnostic agents.
• Material Science: Serves as a precursor for creating specialized polymers or surfaces with tailored carbohydrate functionalities.
• Flavor & Fragrance Industry: Potential use as a precursor for generating specific aroma compounds through controlled hydrolysis and transformation.
• Analytical Standard: Provides a high-purity reference standard for chromatographic (HPLC, GC) and spectroscopic (NMR, MS) analysis in quality control laboratories.

Quality Control

Our β-Gentiobiose Octaacetate is produced under stringent quality management protocols. Each batch is subjected to comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and specific tests for residual solvents and moisture, to ensure it meets the high standards required for research and development. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under anhydrous conditions to prevent hydrolysis and maintain product integrity.
