Widely used as a powerful oxidizing agent in organic synthesis, enabling selective oxidation of alcohols, phenols, and thiols. Commonly applied in the preparation of fine chemicals and pharmaceuticals where controlled oxidation is critical. Also employed in analytical chemistry for redox titrations due to its stable and well-defined oxidation potential. Used in electrochemical processes and as a catalyst in certain polymerization reactions. Its strong oxidizing nature makes it suitable for surface treatment of metals and in some etching processes. Additionally, finds use in the synthesis of nanomaterials and metal oxides, where it acts as a precursor for cerium-based compounds.
