Description

Manganese sulfate (CAS 7785-87-7 ), also sold as manganous sulfate, is an inorganic manganese salt used across agriculture, nutrition, and industrial processing as a concentrated, bioavailable source of manganese. It functions as a micronutrient supplement, catalyst precursor, and process chemical depending on the application sector. In agriculture, it corrects manganese deficiency in crops through foliar sprays and soil amendments. This directly improves yield in cereals, legumes, and fruit crops. Feed and premix manufacturers incorporate it as a trace mineral source in livestock and poultry nutrition programs to ensure optimal animal health. In battery and electronics manufacturing, it serves as a precursor in the synthesis of electrolytic manganese dioxide and cathode materials. Water treatment operations use it to support oxidation processes. These processes are essential for iron and manganese removal from potable water supplies. Manganese sulfate is available as a monohydrate powder, which is the most commercially prevalent form in the market. Higher hydrate forms are also present in some markets. Recognized grades include feed-grade, fertilizer-grade, and technical-grade, with food-grade and pharmaceutical-grade material available for specific needs. These high-purity options meet stricter requirements such as FCC , USP , Ph.Eur. , BP , EP , or ACS standards. Standard packaging ranges from 25 kg bags to bulk quantities for industrial buyers.
