Ammonium Sulphate is an inorganic salt with the formula (NH₄)₂SO₄. It appears as a white crystalline solid, highly soluble in water, and is widely used as a fertilizer due to its high nitrogen and sulfur content. Besides agriculture, ammonium sulphate finds extensive use in industrial processes, food additives, pharmaceutical applications, and water treatment. It acts as a soil amendment to improve nitrogen levels and acidity, a flocculating agent in water purification, and a stabilizer or precipitant in biochemical and pharmaceutical formulations.

Ammonium Sulphate

Primary Uses

Agriculture & Fertilizers

Used predominantly as a nitrogen fertilizer to provide plants with essential nitrogen and sulfur nutrients.
Helps improve soil fertility and crop yields, especially on alkaline soils where it also lowers soil pH.
Commonly applied for cereal crops, vegetables, fruits, and turfgrass.

Industrial Applications

Used as a flame retardant in textiles and paper products.
Acts as a precipitating agent in protein purification and biochemical research.
Utilized as a stabilizer in some pharmaceutical formulations.

Water Treatment

Functions as a flocculant to aid in the removal of impurities and suspended solids from wastewater.
Helps control pH and remove contaminants.

Food Industry

Sometimes used as an acidity regulator and dough conditioner in baking.
Listed as a food additive (E517) in some regions, employed as an anti-caking agent or dough improver.

Secondary Uses

Pharmaceuticals

Used as an excipient and stabilizer in tablet and capsule formulations.
Occasionally used in intravenous solutions to supply ammonium ions.

Laboratory & Research

Used in protein precipitation protocols such as ammonium sulfate precipitation to fractionate proteins by solubility.
Employed as a reagent for analytical chemistry.

Other Niche Applications

Used in the manufacture of flame retardants, dyes, and other chemicals.
Occasionally in textile industry as a mordant.
