Chitosan is obtained by alkaline partial deacetylation of chitin. Degree of deacetylation is the most important characteristic influences the physical, chemical and biological properties of chitosan. The FTIR spectroscopy is simple and precise method used to determine the degree of deacetylation of the chitosan sample. Degree of deacetylation was found to be 78.90±0.904 for the chitosan sample and used further for the drug delivery applications.
