Ammonuim Sulfate
CAS No.: 7783-20-2 Min. Order: 20 metric tons Place of origin: Shandong province, China Industry grade Appearance: Colorless crystal, Ash black lumpish solid Brand name: SHANGXIN Packing: 25 kgs or 50 kgs packed in inside plastic bags with outside woven bags
Ammonium sulfate (IUPAC-recommended spelling; Also ammonium sulphate in British English), (NH4)2SO4, is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer. It contains 21% nitrogen as ammonium cations, and 24% sulfur as sulfate anions.
Uses 1)The primary use of ammonium sulfate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of ammonium sulfate is its low nitrogen content relative to ammonium nitrate, which elevates transportation costs. It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2, 4-D (amine), glyphosate, and glufosinate herbicides.
2)Laboratory use In biochemistry, ammonium sulfate precipitation is a common method for purifying proteins by selective precipitation; Ammonium sulfate is extremely soluble in water and so can make very concentrated solutions which can "salt out" proteins, causing their precipitation at particular concentrations. This provides a convenient and simple means to fractionate complex protein mixtures. As such, ammonium sulfate is also listed as an ingredient for many United States vaccines per the Center for Disease Control.
3)Food additive As a food additive, ammonium sulfate is considered generally recognized as safe (GRAS) by the US Food and Drug Administration, and in the European Union it is designated by the E number E517. It is used as an acidity regulator in flours and breads.
