Used as a catalyst precursor in organic synthesis and industrial oxidation reactions. Employed in the production of manganese-based functional materials, including cathode materials for batteries and manganese dioxide for electronics. Serves as a manganese source in ceramic glazes and glass manufacturing, helping to control color and reduce iron-induced discoloration. Applied in analytical chemistry as a reagent for detecting certain anions. Also utilized in the preparation of catalysts for the petrochemical industry and in environmental applications such as NOx reduction catalysts.
