  • Applications

    Potassium Bromate (CAS 7758-01-2) is primarily used as a flour improver and dough conditioner in bakery applications, where it acts as a powerful oxidizing agent to improve gas retention and crumb structure. It is also employed as an oxidizing agent and synthetic intermediate in industrial manufacturing and organic synthesis. In analytical chemistry, Potassium Bromate serves as an oxidant in redox reactions and related titration methods. In some specialized formulations, it may serve as a bromate source for certain bromination or oxidation steps in the production of specialty chemicals, subject to local regulations and formulation limits.
