Product Description of Ammonium Sulfate CAS#7783-20-2
Ammonium sulfate is an industrial-grade product with a purity of ≥99%, appearing as a white crystalline powder with a slight ammonia odor. It has a melting point of 280℃ (decomposes) and does not have a defined boiling point as it decomposes upon heating. The vapor pressure is less than 1 Pa at 25℃, and its relative density is 1.77 at 20℃.
It is highly soluble in water but insoluble in ethanol and acetone. The compound is stable under normal conditions but is incompatible with strong oxidizing agents and strong bases.

Product Application of Ammonium Sulfate CAS#7783-20-2
Ammonium sulfate is a typical nitrogen-based, water-soluble, and fast-acting fertilizer suitable for a wide range of soils and crops. It is widely used as an artificial fertilizer, particularly for alkaline soils. In the soil, it releases ammonium ions that generate a mild acidic effect, helping to reduce soil pH while supplying essential nitrogen to support plant growth.
