Chitosan is a natural polysaccharide derived from chitin, used in biomedical applications, drug delivery, water treatment, and agriculture due to its biocompatibility and antimicrobial properties. It has a CAS number of 9012-76-4, molecular formula (C6H11NO4)n, and is a polymer with no defined molecular weight. It is stable at ambient storage conditions and carries no signal word. Molekula supplies Chitosan from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
