Description

Manganese sulfate monohydrate (CAS 10034-96-5 ), also sold as manganous sulfate monohydrate, is an inorganic manganese salt used across agriculture, food, and industrial sectors as a micronutrient source and process chemical. It supplies bioavailable manganese in applications ranging from crop nutrition to fermentation media and chemical synthesis. In agriculture and animal feed, it corrects manganese deficiency in soils and livestock diets. This directly improves crop yield and feed nutritional profiles. Food and beverage manufacturers use it as a mineral fortification ingredient in functional foods, dietary supplements, and infant formula for nutritional support. In industrial biotechnology, it supports microbial fermentation processes as a cofactor source, influencing enzyme activity and cell growth in production-scale bioreactors. This is essential for high-yield manufacturing. Chemical producers also use it as a catalyst precursor in oxidation reactions and as a raw material for synthesizing other manganese compounds. Manganese sulfate monohydrate is supplied as a pale pink crystalline powder. Standard grades include feed-grade, food-grade meeting FCC specifications, and technical-grade for industrial use. These variations ensure the material meets the specific purity requirements of the end application. Pharmaceutical and reagent grades are available for life science and analytical applications where purity thresholds are more stringent. These often comply with USP , Ph.Eur. , BP , or EP standards. Additionally, high-purity versions may meet ACS requirements for laboratory use. This versatility makes it a staple chemical for global manufacturers across diverse technical and nutritional industries. Contact us for supply of Manganese sulfate monohydrate Request Quote
