Useful:

• Description: Chitobiose is a dimer of β-1,4 linked glucosamine units derived from chitin, which, in turn, is a long chain polymer of N-acetylglucosamine that is a primary component of fungal cell walls and arthropod exoskeletons. Chitobiose octaacetate is a form of chitobiose containing eight acetate groups. It is formed by the acetolysis of chitin. Chitobiose octaacetate can be used for the synthesis of chitobiose oxazoline and other chitin precursors.
• Uses: Chitin derivatives
