Product Introduction: This product is a mucopolysaccharide extracted from the intestinal mucosa of pigs. It is the calcium salt of sulfated chondroitin sulfate, obtained by nitrous acid cleavage and subsequent purification of sodium heparin.

This product is a white or off-white powder with strong hygroscopic properties. It is insoluble in organic solvents such as ethanol and acetone, but readily soluble in water. The molecule is acidic and carries multiple negative charges; it can react with cations to form salts. The weight-average molecular weight is less than 8,000 Da, and the fraction with a weight-average molecular weight below 8,000 Da accounts for at least 75% of the total composition.
