Used as a precursor in the synthesis of manganese-based catalysts, especially for oxidation reactions in industrial processes. Commonly employed in the production of mixed oxide catalysts used in the removal of nitrogen oxides (NOx) from exhaust gases. Also utilized in the preparation of manganese dioxide for battery materials and as a catalyst in organic transformations. Applied in ceramic and glass manufacturing to impart color and improve quality. Serves as a manganese source in chemical vapor deposition for functional thin films. Used in laboratories for analytical chemistry and in the formulation of specialty chemicals requiring soluble manganese salts.
