CAS 9012-76-4: Chitosan

Description: Chitosan is a biopolymer derived from chitin, which is found in the exoskeletons of crustaceans such as shrimp and crabs. It is characterized by its white to off-white powdery appearance and is soluble in acidic solutions, making it distinct from its precursor, chitin, which is insoluble in water. Chitosan exhibits several notable properties, including biocompatibility, biodegradability, and non-toxicity, which make it suitable for various applications in medicine, agriculture, and food industries. Its ability to form gels and films allows for its use in drug delivery systems, wound dressings, and as a food preservative. Additionally, chitosan possesses antimicrobial properties, which can inhibit the growth of certain bacteria and fungi. The degree of deacetylation, which refers to the proportion of acetyl groups removed from the chitin structure, significantly influences its solubility and functional properties. Overall, chitosan is a versatile and environmentally friendly material with a wide range of potential applications.
