Used as an oxidizing agent in organic synthesis, particularly in the oxidation of alcohols and phenols. Employed in analytical chemistry for titrations due to its stable redox properties. Acts as a catalyst or catalyst precursor in industrial processes, including automotive exhaust treatment and petroleum refining. Applied in the preparation of cerium-doped materials for use in UV-absorbing coatings and glass polishing. Also utilized in electrochemical applications, such as in the formulation of electrolytes for certain types of fuel cells and batteries.
