Chitosan with CAS 9012-76-4
What is Chitosan?
Chitosan is a natural biopolymer derived from chitin, which is extracted from crustacean shells such as shrimp and crab. As a linear polysaccharide, chitosan consists of randomly distributed β-(1-4)-linked D-glucosamine and N-acetyl-D-glucosamine units. This biodegradable and biocompatible polymer has gained significant attention across various industries due to its exceptional properties.
Our chitosan products are manufactured using advanced processing technology, ensuring high purity, consistent quality, and excellent solubility. Available in various molecular weights and deacetylation degrees, our chitosan can meet diverse application requirements across pharmaceutical, agricultural, water treatment, cosmetic, and food industries.
