Ammonium sulphate is a white, crystalline solid that is used as a fertilizer and in the manufacture of paper. Ammonium sulphate is an ammonium salt of sulfuric acid with the chemical formula NH4HSO4. It is most often used as a fertilizer, although it has many other uses. Ammonium sulfate enhances the absorption of water vapor by plants, which increases their ability to grow. The optimum concentration for ammonium sulfate is from 20-40 g/L. Ammonium sulfate also increases the rate of synthesis of RNA and proteins in cells. This may be because it provides sulfur for enzymes involved in energy metabolism and protein synthesis. Ammonium sulfate has been shown to have synergistic effects with zirconium oxide, allowing more rapid dissolution in water than would be expected from its solubility alone. Ammonium sulfate reacts with bowel disease causing inflammation and ulceration due to its effect on bowel flora (e

Reagecon's 2M Ammonium Sulphate (NH₄)₂SO₄ Double Junction Electrode Filling Solution must be used in the outer chamber of a double junction reference electrode for pH or ion measurement, in situations where Potassium Chloride or Potassium Nitrate should not be used. Chloride (Cl-) anions can form insoluble precipitates with Hg++, Cu++, Ag+ or Pb++ which will block the diaphragm of a single junction reference electrode. Potassium may react with anions such as perchlorate (ClO₄¯) to form Potassium Perchlorate (KClO₄). In these situations Reagecon's 2M Ammonium Sulphate Double Junction Electrode Filling Solution is an ideal compromise. - A good electrolyte must fulfil a number of conditions. The equitransference of the cation/anion combination should be as close as possible to being equimobile, have constant chloride activity, be of high electrical conductance and be as non-chemically reactive as possible. Reagecon 2M Ammonium Sulphate Double Junction Electrode Filling Solution is a high quality product that fulfils most of these criteria. However, as outlined above the use of Chloride or Potassium in the electrolyte is precluded for certain types of samples. In such instances Reagecon 2M Ammonium Sulphate Double Junction Electrode Filling Solution, is an ideal substitute.

Ammonium sulfate is widely utilized as a fertilizer for alkaline soils. In biochemistry it is used for purification of proteins via ammonium sulfate precipitation method. As a food additive, it serves as an acidity regulator in flours and breads. It is used in the preparation of other ammonium salts, particularly ammonium persulfate. It is applied in several applications as a flame retardant and a wood preservative. It finds use as raw materials for various chemical products such as dyes and pharmaceutical products. A saturated solution of ammonium sulfate in heavy water is employed as an external standard in sulfur-33 NMR spectroscopy.
