Product Uses

Ammonium sulfate is primarily used as a nitrogen-sulfur fertilizer in agriculture. Industrially, it functions as a flame retardant, protein precipitant, and chemical synthesis precursor. In food processing, it acts as a dough conditioner (E517), while in laboratories, it serves as a buffer and reagent. Additional roles include water treatment, leather tanning, and electroplating.

Ammonium Sulfate (NH₄)₂SO₄ Primary Uses

1. Fertilizer

   • As a high-efficiency nitrogen (21%) and sulfur (24%) fertilizer, it provides essential nutrients for crop growth, particularly in alkaline soils where sulfur supplementation is critical.

   • Preferred for chloride-sensitive crops (e.g., tobacco, citrus) due to its low chloride content.

2. Industrial Applications

   • Flame retardant: Acts as a fire-suppressing additive in textiles and wood products by promoting char formation and reducing flammability.

   • Chemical synthesis: Serves as a raw material for producing ammonium persulfate (a key oxidizer in polymer initiation) and other ammonium compounds.

   • Protein purification: Used as a precipitating agent in biotech/lab settings for isolating proteins via "salting out."
