Used as a catalyst in chemical synthesis, particularly in oxidation reactions. Employed in dry cell batteries to prevent hydrogen buildup and improve performance. Serves as a precursor for other manganese compounds in industrial processes. Applied in agriculture as a micronutrient in fertilizers to correct manganese deficiency in soils. Utilized in animal feed supplements to support metabolic functions. Plays a role in water treatment for removing contaminants. Also used in some electroplating baths to produce manganese coatings.
