Used as a precursor in the production of fertilizers and animal feed supplements to correct manganese deficiencies in soil and livestock. Widely employed in the synthesis of other manganese compounds, including catalysts and pigments. Commonly utilized in the electroplating industry to deposit manganese coatings on metals for corrosion resistance and hardness. Serves as a reducing agent in chemical manufacturing processes. Also applied in the preparation of dry cell batteries and as a nutritional additive in plant growth media.
