Product Overview
Chitosan 75% derived from shrimp shells is a high-purity biopolymer obtained through controlled deacetylation of chitin, ensuring consistent molecular weight and degree of deacetylation. This water-soluble polysaccharide exhibits exceptional biocompatibility, biodegradability, and mucoadhesive properties, making it a versatile material for advanced research applications. The product maintains a fine, free-flowing powder form with a characteristic off-white to pale yellow appearance, ensuring easy dissolution in dilute acidic solutions. Its high degree of deacetylation (75%) enhances its cationic nature, enabling strong electrostatic interactions with anionic polymers and biomolecules. The material demonstrates excellent film-forming capabilities and thermal stability up to 200°C, while remaining non-toxic and environmentally friendly. Chitosan’s unique structural properties allow for controlled modification through chemical cross-linking or functional group attachments, expanding its potential in specialized research formulations. Each batch undergoes rigorous quality control to ensure minimal heavy metal content (<10 ppm) and consistent viscosity parameters, providing reliable performance in sensitive experimental protocols.
FAQs
1. What is the solubility profile of this 75% chitosan?
This chitosan grade dissolves readily in dilute acetic acid solutions (1-2%) and other organic acids. It remains insoluble in water, alkali solutions, and most organic solvents unless chemically modified.
2. How does the 75% deacetylation level affect its properties compared to higher grades?
The 75% deacetylation provides balanced solubility and cationic charge density. Higher grades (>85%) offer increased solubility but may compromise mechanical strength in certain applications, while this grade maintains optimal performance for most research needs.
3. What is the typical molecular weight range for this chitosan product?
This chitosan typically falls in the medium molecular weight range of 100,000-300,000 Da, offering a practical balance between solution viscosity and film-forming capabilities for most laboratory applications.
4. Are there any special storage requirements for maintaining product integrity?
Store in a cool, dry environment below 25°C in tightly sealed original packaging. Exposure to moisture can cause premature degradation, while prolonged light exposure may lead to slight discoloration without affecting performance.
5. What quality control measures are implemented for this chitosan product?
Each batch undergoes FTIR spectroscopy for structural confirmation, viscosity testing in 1% acetic acid, and heavy metal analysis via ICP-MS. Microbial contamination is controlled through gamma irradiation when required for specific applications.
