Chitin Specification

The Chitin, with the CAS registry number 1398-61-4, is also known as Chitan, N-acetyl-. Its EINECS registry number is 215-744-3. This chemical's molecular formula is (C8H13NO5)n. Its systematic name is called Chitin. When you are using this chemical, please be cautious about it. You must avoid contact with skin and eyes. Chitin is a long-chain polymer of a N-acetylglucosamine

Chitosan is derived from chitin, which is used as a biocontrol elicitor in agriculture and horticulture. Chitin is used in industry in many processes. It is used as an additive to thicken and stabilize foods and pharmaceuticals. It also acts as a binder in dyes, fabrics, and adhesives. Industrial separation membranes and ion-exchange resins can be made from chitin. Processes to size and strengthen paper employ chitin. Chitin's properties as a flexible and strong material make it favorable as surgical thread. Its biodegradibility means it wears away with time as the wound heals. Moreover, chitin has some unusual properties that accelerate healing of wounds in humans.

The toxicity data is as follows:
