Overview

Manganese(2+) sulfate (CAS 7785-87-7) is an inorganic salt compound with essential micronutrient properties and industrial catalytic applications. This manganese compound represents a crucial source of manganese ions in various industrial and agricultural applications. As an inorganic sulfate salt, manganese(2+) sulfate demonstrates excellent solubility in water, making it particularly valuable for formulations requiring readily bioavailable manganese. The compound typically appears as pale pink to colorless crystalline material, often encountered in its monohydrate or tetrahydrate forms depending on crystallization conditions. From a safety perspective, manganese(2+) sulfate requires careful handling due to its STOT RE 2 classification, indicating potential for specific target organ toxicity following repeated exposure. The GHS08 pictogram reflects health hazards associated with prolonged exposure, while the GHS09 designation highlights environmental concerns, particularly regarding aquatic ecosystems with its Aquatic Chronic 2 classification. Transport regulations classify this material under ADR Class 9 as a miscellaneous dangerous substance. Industrial applications primarily center on fertilizer production, where manganese(2+) sulfate serves as an essential micronutrient supplement for crops, particularly in manganese-deficient soils. The compound also functions as a catalyst in various chemical processes and finds use in animal feed formulations to prevent manganese deficiency. Unlike specialized organic compounds such as 2-methyl-N-[3-(trifluoromethyl)phenyl]propanamide used in pharmaceutical applications, manganese(2+) sulfate serves broader industrial needs where manganese supplementation is required. OYSI maintains reliable supplies of technical-grade manganese(2+) sulfate to support diverse European industrial applications requiring consistent manganese content and quality specifications.
