Used as a precursor in the synthesis of other manganese compounds and as a catalyst in organic reactions, including oxidation processes. Employed in dry cell batteries and electrochemical cells to prevent polarization. Serves as a nutritional supplement in animal feed and plant fertilizers to support metabolic functions and address manganese deficiencies. Applied in textile printing and dyeing, as a dopant in phosphors for lighting, and in electroplating baths to deposit manganese coatings on metals.
