What is the molecular weight of Chitosan, Product 419419?
Although we do not measure molecular weight on a batch to batch basis, we would expect it to be approximately 310,000 to >375,000 based on the viscosity range of 800-2000 mPaS.
What is the particle size of Product 419419, Chitosan?
The particle size has not been determined. It is described as being course ground flakes or powder.
What is the solubility of Product 419419, Chitosan?
Chitosan is insoluble in water or organic solvents. Hazy suspensions can be prepared in 1M acetic acid at a concentration of 10 mg/mL, but extensive sonication may be required to fully suspend the material.
What is the source of Product 419419, Chitosan?
Chitosan is a natural biopolymer commerically derived from chitin from crustacean shells.
What is the pH of Product 419419, Chitosan?
Our supplier estimates that the pH falls within the range of 6.5-8.0.
What are some uses for chitosan?
Chitosan is a biocompatible, antibacterial and environmentally friendly polyelectrolyte with a variety of applications including water treatment, chromatography, additives for cosmetics, textile treatment for antimicrobial activity, novel fibers for textiles, photographic papers, biodegradable films, biomedical devices, and microcapsule implants for controlled release in drug delivery. Please note that Product No. 419419 is for research purposes only, not for cosmetic or drug use.
