Manganese Sulphate CAS 7785-87-7 powder granular
Manganese Sulphate is a widely used inorganic compound with multiple industrial and agricultural applications. It is also known by several common aliases, including Manganese(II) sulfate, Manganese sulfate monohydrate, Manganous sulfate, and Sulfuric acid manganese(II) salt. The chemical formula of Manganese Sulphate is MnSO4, and its CAS number is CAS 7785-87-7.


Product Properties
Manganese Sulphate exists in two main forms: anhydrous and hydrous (most commonly monohydrate and tetrahydrate). The most widely used form is the monohydrate, which appears as light pink to rose-colored powder or granular solid. It is soluble in water, slightly soluble in methanol, and insoluble in ethanol. The physical properties of Manganese Sulphate include a molecular weight of 151.00 (anhydrous) or 169.01 (monohydrate), a melting point of 700°C (anhydrous), and a density of 2.95 g/cm³ (anhydrous). It is non-toxic but should be handled with proper protective measures to avoid irritation.
