Manganese(2+) sulfate

Manganese(2+) sulfate is an inorganic chemical compound with the formula MnO4S and CAS number 7785-87-7. This manganese salt has a molecular weight of 151 g/mol and appears as crystalline solid. It is classified as a hazardous substance with STOT RE 2 and Aquatic Chronic 2 properties, requiring careful handling and storage. The compound carries GHS08 and GHS09 pictograms with a warning signal word.

Manganese(2+) sulfate typically appears as pale pink to light brown crystalline powder or crystals at room temperature. The compound is highly soluble in water, forming characteristic pink-colored solutions. It has a molecular weight of 151 g/mol and is odorless under normal conditions. The substance is hygroscopic, meaning it readily absorbs moisture from air, and decomposes at elevated temperatures.

Manganese(2+) sulfate serves as an essential micronutrient source in fertilizers for agricultural applications, helping prevent manganese deficiency in crops. Industrial applications include its use as a catalyst in chemical synthesis, a component in animal feed supplements, and in the production of manganese-based chemicals. It is also utilized in electroplating processes and as a raw material for manufacturing other manganese compounds.

Manganese(2+) sulfate requires appropriate personal protective equipment including safety goggles, dust masks, and chemical-resistant gloves during handling. Work in well-ventilated areas to minimize inhalation exposure, as the substance is classified as STOT RE 2. Avoid generating dust and prevent contact with skin and eyes. Use proper industrial hygiene practices and ensure workers are trained on the specific hazards associated with repeated exposure.

Manganese(2+) sulfate should be stored in a cool, dry, well-ventilated area away from incompatible materials. Keep containers tightly sealed to prevent moisture absorption due to its hygroscopic nature. Store away from strong oxidizers and alkaline substances. Ensure storage areas have appropriate containment measures to prevent environmental release, considering its Aquatic Chronic 2 classification. Maintain temperatures below decomposition point.

In case of skin contact with manganese(2+) sulfate, immediately remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with plenty of clean water for 15 minutes and seek medical attention. If inhaled, move person to fresh air and seek medical advice if respiratory irritation occurs. Call emergency services if serious exposure symptoms develop.

Manganese(2+) sulfate disposal must comply with local and national waste regulations as a hazardous chemical waste. The substance cannot be disposed of in regular waste streams due to its environmental hazard classification (Aquatic Chronic 2). Contact licensed waste management companies specialized in inorganic chemical waste disposal. Small quantities may require neutralization and treatment before disposal, following environmental protection guidelines and obtaining proper disposal documentation.

Manganese(2+) sulfate is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transportation purposes. Packages must be properly labeled with appropriate hazard markings and transport documentation. Use UN-approved packaging suitable for Class 9 materials. Vehicles must carry appropriate emergency equipment and drivers need ADR certification. Ensure compliance with international dangerous goods transport regulations for road, rail, or sea transport.

Manganese(2+) sulfate is subject to European REACH and CLP regulations requiring proper classification, labeling, and safety data sheet provision. While not listed as SVHC (Substance of Very High Concern), it requires compliance with occupational exposure limits and environmental release reporting. Industrial users must implement risk management measures for STOT RE 2 classification and aquatic environmental protection. National chemical safety regulations may impose additional requirements.
