CAS 83512-85-0: N-Carboxymethylchitosan

Carboxymethyl chitosan has good solubility in water and unique chemical, physical and biological properties such as high viscosity, large hydrodynamic volume, low toxicity, biocompatibility and good ability to form films, fibres and hydrogels. For this reason, it has been extensively used in many biomedical fields such as a moisture-retention agent, bactericide, wound dressing agent, in artificial bone and skin, as blood anticoagulant and as a component in different drug delivery matrices. The reactive ligands COOH and NH2 groups are available for metal chelation and dye binding.
