Ch-T depended on the pH of the reaction mixture used in different medium neutral, acidic or alkaline media. It gave hypohalous acid (HOCl) in acidic medium that undergoes further hydrolysis to give H2OCl+. The HOCl or H2OCl+can oxidize the iodine to the oxidative state I+ and thus rapidly reacts with any sites within ligand that can undergo electrophilic substitution reactions. In alkaline solutions of Ch-T became HOCl and ClO with the formation of hypoiodite ion (IO-) and iodate (IO-3) ions.
