How is chitosan sold? What is the price?

Customer Service:

Chitosan, also known as chitin, poly(beta-(1,4)-2-amino-2-deoxy-D-glucose), or poly(beta-(1,4)-D-glucosamine), is a natural biopolymer derived from chitin. It is commonly used in biochemical research, drug delivery systems, tissue engineering, and as a flocculant in water treatment. It's available in various forms such as powder, granules, and solutions.
