Used as a precursor in the synthesis of other manganese compounds and as a catalyst in organic reactions. Employed in dry cell batteries to enhance conductivity and performance. Serves as a source of manganese in fertilizers and animal feed supplements to correct manganese deficiencies in soil and livestock. Utilized in the textile industry for dyeing processes and as a weighting agent for silk. Applied in ceramics and glass manufacturing to modify color and improve quality. Also used in some electroplating solutions and in laboratory research for biochemical assays involving manganese-dependent enzymes.
