What is the Chitosan ?
Chitosan is a natural polysaccharide derived from the chitin found in the exoskeletons of shellfish, such as crabs, lobsters, and shrimp. Structurally, it is a linear polysaccharide composed of β-linked D-glucosamine and N-acetyl-D-glucosamine units. The primary method for obtaining chitosan involves treating the chitin shells with an alkaline substance, typically sodium hydroxide, to deacetylate the chitin, converting it to chitosan.
Chitosan is unique for being the only natural polycation (positively charged polymer), a feature that gives it exceptional properties, including high solubility in acidic environments and the ability to chelate metal ions. The degree of deacetylation (DD) plays a crucial role in its solubility, molecular weight, and other functional properties, with a DD of up to 0.95 achievable in typical production processes.
What is the CAS number for Chitosan ?

What is Chitosan (9012-76-4) used for?
Chitosan’s ability to chelate heavy metals and its biodegradability make it ideal for use in water purification processes. Chitosan is used as a drug delivery vehicle due to its biocompatibility and ability to enhance the bioavailability of active ingredients. Its antibacterial properties and ability to form protective films make it a component in wound dressings and medical devices. Chitosan is also used in textiles, food packaging, and coatings due to its biodegradable, antimicrobial, and film-forming properties. The global chitosan market, valued at USD 6.8 billion in 2019, is expected to grow significantly (CAGR of 24.7%) due to its increasing application in high-value sectors such as water treatment, cosmetics, and pharmaceuticals. Despite its advantages, chitosan's limited solubility in neutral and basic pH environments restricts its use in certain biomedical applications, such as in physiological pH conditions (pH 7.4). As a result, researchers have developed modified chitosan derivatives with enhanced solubility.
