Used as a precursor in the synthesis of manganese-based catalysts, especially for oxidation reactions in industrial processes. Commonly employed in the production of manganese dioxide and other manganese oxides used in batteries and electronic materials. Applied in ceramic and glass manufacturing to introduce manganese into formulations, influencing color and UV absorption properties. Serves as a catalyst component in the manufacture of fine chemicals and in environmental applications for treating sulfur compounds. Also utilized in analytical chemistry as a reagent for detecting certain anions. Additionally, employed in agriculture as a soluble source of manganese for fertilizers and foliar nutrient supplements in manganese-deficient soils.
