CAS Number: 7782-63-0
Ferrous Sulphate Heptahydrate is a water-soluble inorganic iron salt supplied as pale green to blue-green crystals. It has the molecular formula FeSO₄·7H₂O, CAS number 7782-63-0 and molecular weight of approximately 278.02 g/mol. The product is commonly used as a soluble source of ferrous iron in agricultural micronutrient formulations, fertilizer manufacturing, soil treatment, water and effluent treatment, cement processing, pigment production and other industrial chemical applications. Fertilizer-grade Ferrous Sulphate Heptahydrate commonly contains a minimum of 19% ferrous iron as Fe. Pure FeSO₄·7H₂O theoretically contains approximately 20.09% elemental iron; however, the guaranteed commercial iron content must be confirmed through the product’s batch-specific Certificate of Analysis. Mangalam Acid & Chemicals supplies Ferrous Sulphate Heptahydrate from Vapi, Gujarat, India, for bulk agricultural and industrial requirements. Buyers can request a quotation, product documentation and the latest Certificate of Analysis to confirm ferrous iron, free acidity, ferric iron, moisture and water-insoluble matter before use.
