Used as a precursor in the synthesis of other manganese compounds and as a catalyst in various organic reactions. Commonly employed in electroplating processes to deposit manganese coatings on metals, enhancing corrosion resistance and wear properties. Utilized in the production of dry cell batteries as an electrolyte component. Applied in biological and biochemical research as a source of manganese ions in enzyme studies and cell culture media. Also used in textile printing and as a moisture-absorbing agent in certain industrial applications.
