Request SDS →Ammonium sulfate (CAS 7783-20-2), abbreviated AS, is a crystalline inorganic salt. It is used as a nitrogen-and-sulfur fertilizer, as a flame-retardant additive for fabrics and paper, in tanning and galvanizing, in water treatment, and as a protein-precipitation reagent.
Frequently Asked Questions
What is ammonium sulfate used for?
Ammonium sulfate (AS) is a crystalline inorganic salt used as a nitrogen-and-sulfur fertilizer, as a flameproofing additive for textiles and paper, in leather tanning and galvanizing baths, in water treatment for coagulation and chloramine formation, and as a protein-precipitation and fractionation reagent in bioprocessing. CAS 7783-20-2. It is supplied in industrial and fertilizer grades.
Is ammonium sulfate the same as Epsom salt?
No. Ammonium sulfate is (NH4)2SO4, an ammonium salt used mainly as a nitrogen-sulfur fertilizer, while Epsom salt is magnesium sulfate (MgSO4). They are different compounds with different cations and uses despite both being sulfate salts. Confirm identity by CAS 7783-20-2 on the product documentation.
What is the chemical formula and CAS number of ammonium sulfate?
Ammonium sulfate is (NH4)2SO4 (CAS 7783-20-2), with a molar mass of about 132.14 g/mol, classified under HS code 3102.21. It is supplied as a crystalline solid. Identity and assay are confirmed on the CoA.
Is ammonium sulfate available as a liquid solution?
Ammonium sulfate is highly water-soluble and can be supplied or formulated as an aqueous solution as well as the crystalline solid, depending on the application such as foliar fertilizer or process dosing. Confirm the form and concentration that fit your process. Request the matching SDS and CoA.
How is bulk ammonium sulfate packaged and priced?
AS is supplied in bags, supersacks, and bulk to manufacturers and growers. Pricing depends on grade, particle size, and volume, so request a bulk quote rather than a list price. The SDS and CoA are provided with the quote.
