Iodic acid is primarily used in analytical chemistry as a strong oxidizing agent. It is employed in the determination of various substances, such as the quantification of sulfur in organic compounds. Additionally, it serves as a key reagent in the synthesis of iodine-based compounds, which are essential in pharmaceuticals and disinfectants. In the field of organic chemistry, it is utilized for the oxidation of alcohols to aldehydes or ketones. Furthermore, iodic acid is applied in the preparation of iodates, which are used in the food industry as dough conditioners and in the production of iodized salt to prevent iodine deficiency disorders. Its strong oxidative properties also make it useful in certain types of chemical research and industrial processes.
