CAS No.: 9012-76-4
Molecular formula: C₆H₁₁NO₄X₂
Molecular weight: 161.16
EINECS No.: 618-480-0.
Description
Chitosan is obtained by deacetylation of chitin and is a biodegradable, biocompatible and non-toxic polymer.
Features
High Purity
The product appears as a white to off-white powder with controllable purity.
Adjustable Solubility
Soluble in dilute acidic solutions; solubility and viscosity can be controlled by the degree of deacetylation (typically 75-95%).
Wide Molecular Weight Range
A broad molecular weight range (50-1000 kDa) allows for customization for specific applications.
Natural Antimicrobial Properties
Possesses inherent antibacterial and antifungal activity and is stable in solid form.

FAQ
Q: What is Chitosan?
A: Chitosan is a biodegradable polysaccharide derived from chitin. It appears as a white to off-white powder and is widely used in pharmaceuticals, food, water treatment, and cosmetics.
Q: What is the CAS number and molecular formula?
A: CAS number is 9012-76-4, molecular formula (C6H11NO4)n, molecular weight varies with deacetylation degree. Buyers use this for regulatory and sourcing documentation.
Q: What are the key specifications to check?
A: Important specs include degree of deacetylation (≥ 85% common), viscosity, molecular weight, and moisture content (≤ 10%). These affect solubility and performance in applications.
Q: What forms is Chitosan supplied in?
A: Typically supplied as powder or flakes, sometimes granules, in 25–50 kg kraft paper or PE-lined bags. Proper packaging prevents moisture uptake and degradation.
Q: What are the main applications for buyers?
A: Used in water purification, dietary supplements, drug delivery, wound dressings, and cosmetic formulations. Application determines required purity and molecular weight.
Q: How soluble is Chitosan?
A: Soluble in dilute acids (like acetic acid), insoluble in water and most organic solvents. Solubility is crucial for formulation and processing.
Q: What storage conditions are required?
A: Store in a cool, dry place, away from strong oxidizers and moisture. Keep containers tightly sealed to prevent clumping and degradation.
Q: Are there handling precautions?
A: Avoid dust inhalation. Use gloves, masks, and goggles when handling. Ensure adequate ventilation in storage and processing areas.
Q: What factors affect purchasing decisions?
A: Degree of deacetylation, molecular weight, purity, form, packaging, and supplier reliability are key. These impact performance, cost, and storage requirements.
Q: How is Chitosan quality verified?
A: Quality is verified through COA, MSDS, solubility tests, viscosity, moisture content, and degree of deacetylation. Certificates from the supplier ensure consistent performance.
