  • Applications

    Potassium Iodate (CAS 7758-05-6) is commonly used as the iodine source for iodized salt in the food industry, helping prevent iodine deficiency; it also serves as a micronutrient supplement in animal feeds. In analytical chemistry, it is employed as a stable oxidizing reagent for iodometric titrations and for generating iodine in situ in various assays. In organic synthesis, it functions as an oxidizing agent and as a source of iodine for preparing iodinated intermediates. In chemical manufacturing, it may be used as a reagent in iodine-mediated oxidation or iodination steps and as a precursor to other iodine-containing compounds. Use is subject to local regulations and formulation limits.
