Product Overview & China Production Capacity
Manganese Sulphate (CAS 7785-87-7, molecular formula MnSO₄·H₂O, MW 169.01) is an essential trace mineral compound used in pharmaceutical applications as a manganese source in nutritional supplements, parenteral nutrition solutions, and multivitamin-mineral formulations. Manganese is a critical cofactor for mitochondrial superoxide dismutase (MnSOD), arginase, and pyruvate carboxylase enzymes. Pharmaceutical-grade manganese sulphate is also used in diagnostic contrast agents and as a reagent in pharmaceutical analysis.
China is the world’s dominant manganese sulphate producer with annual capacity exceeding 2 million MT, primarily serving battery, feed, and industrial markets. Our pharmaceutical-grade facility in Guizhou Province — located in China’s premier manganese ore region — produces 15,000 MT/year of high-purity manganese sulphate monohydrate through electrolytic purification and controlled crystallization from premium manganese carbonate ores.
Manufacturing Standards & Quality Assurance
Production is quality-certified with ISO 9001:2015 quality management. The product meets USP/NF, EP, BP, and ChP monograph specifications for Manganese Sulfate Monohydrate. Our electrolytic purification process removes iron, lead, cadmium, arsenic, and other heavy metal impurities to levels well below pharmacopeial limits, achieving pharmaceutical purity from natural mineral feedstocks.
Quality control includes assay by complexometric titration, identification reactions, pH, loss on drying, iron, lead, cadmium, arsenic, mercury, heavy metals, insoluble matter, chloride, and microbial limits. ICP-MS multi-element screening ensures compliance with ICH Q3D elemental impurity guidelines. Full stability data is maintained per ICH requirements.
