Product Description of Stannous Sulfate CAS No. 7488-55-3
Industrial-grade tin(II) sulfate has a purity of ≥99% and appears as a white, odorless crystalline powder. It decomposes at a melting point of 360 °C, with no determined boiling point due to decomposition. The compound has negligible vapor pressure at 25 °C and a relative density of 4.15 at 20 °C. Tin(II) sulfate is soluble in water (though it easily hydrolyzes), slightly soluble in dilute acids, and insoluble in ethanol. It is chemically stable under normal conditions but is incompatible with strong oxidizing agents and strong bases.
