Manganese Sulphate (CAS 7785-87-7) is a pale pink inorganic salt available in Technical Grade, highly soluble in water and used as a micronutrient source in fertilizers and livestock feed premixes, and industrially as a drier in oil-based coatings and a catalyst in chemical synthesis. It is highly soluble in water, ensuring rapid availability of manganese ions for biological and chemical processes.
In agriculture, it serves as a critical fertilizer component to correct manganese deficiencies in soil, enhancing plant photosynthesis and nitrogen metabolism. The High Purity of the monohydrate form prevents heavy metal contamination in sensitive crop and livestock applications.
The product is also used industrially as a drying agent for paints and varnishes and as a catalyst in chemical synthesis. Its Technical Grade variant is valued for its consistent quality in the production of manganese-based pigments and fungicides.
