Used as a precursor in the synthesis of other manganese compounds and as a catalyst in organic reactions. Commonly employed in electroplating processes to deposit manganese coatings on metals for corrosion resistance and improved surface properties. Serves as a source of manganese in nutritional supplements and animal feed due to its bioavailability. Utilized in the textile industry for dyeing and printing fabrics, where it helps fix colors. Applied in laboratory settings as a reagent for analytical chemistry and in the preparation of buffer solutions. Also used in some battery systems and in environmental studies to examine metal ion behavior in aqueous systems.
