Ammonium sulphate by Research Lab Fine Chem Industries is a high grade reagent. Also known as Diammonium sulphate, this is an inorganic salt. This reagent is available as a fine crystalline white powder which is soluble in water and insoluble in acetone, alcohol and ether. It has a melting point of 235 to 280 C at which it decomposes. Ammonium sulphate is generated by treating ammonia with sulphuric acid. CAS No.: 7783-20-2 Quantity Provided: 500 gm per bottle Molecular Formula: (NH4)2SO4 Molecular Weight: 132.14 Assay: Minimum 98.5 %Ammonium sulphate has a variety of applications in chemical and biological sectors. This compound is extensively used as a fertilizer for alkaline soils. Ina agriculture, it is additionally sprayed as an adjuvant for water-soluble insecticides, herbicides, and fungicides. In laboratories, ammonium sulphate is majorly employed in protein purification by precipitation. It has been used in the preparation of Blue Silver colloidal Coomassie stain for proteins. It is used as E517 in the food industry, as an acidity regulator in flours and breads. It may additionally be employed in the preparation of other ammonium salts, especially ammonium persulfate. This reagent is suitable for industrial synthesis of products and research applications.
