Perichromism: A powerful tool for probing the properties of cellulose and its derivatives

► Using perichromic indicators for investigating cellulose and its derivatives. ► Perichromism is a simple and powerful tool to gain information on the medium. ► Provides information on polarity, acidity, basicity, dipolarity/polarizability. ► Perichromic properties correlate well with DS of cellulose derivatives.
