Sourcing Ammonium Sulfate (Fertilizer/Tech Grade)? ChemicalDekho connects you with major producers like GSFC and FACT (often produced as a byproduct of Caprolactam). Secure bulk supplies for agriculture and industrial applications.
Ammonium Sulfate (CAS 7783-20-2) is a popular fertilizer providing both Nitrogen (21%) and Sulfur (24%). It is particularly effective in alkaline soils where it lowers pH. In the chemical industry, it serves as a flame retardant additive and a precipitating agent for protein purification in biotechnology.
Listings include both pure white crystalline material (Technical) and off-white/brownish granules (Fertilizer grade).

Generally considered safe. Dust causes mild respiratory irritation. May cause eye irritation. Decomposes if heated strongly to release ammonia.
The ammonium ion releases a small amount of acid, which helps lower the pH of alkaline soils, making nutrients more available to plants.
Yes, huge quantities are produced as a co-product during the manufacture of Caprolactam (for Nylon). This makes it very cost-effective.
No. Fertilizer grade contains impurities (iron, organic matter) that make it off-white. Lab use requires >99% pure white crystals.
It is stable, but it can cake (harden) if exposed to moisture. If kept dry, it lasts indefinitely.
