Sodium persulphate by Research Lab Fine Chem Industries is a high grade reagent. Also known as Sodium peroxodisulfate, this is the sodium salt of peroxydisulfuric acid. The reagent is available as a white power which is soluble in water. It has a melting point of 180 C at which it decomposes. Sodium persulphate can be generated by the electrolytic oxidation of sodium hydrogen sulphate. While it is stable under general conditions, this reagent is incompatible with strong oxidizing agents. CAS No.: 7775-27-1 Quantity Provided: 500 gm per bottle Molecular formula: Na2S2O8 Molecular weight: 238.10 Assay: Minimum 99 Analytical grade reagentSodium persulphate has a variety of applications in chemical and biological sectors. This reagent finds applications in the organic synthesis of various derivative compounds. Sodium persulphate is broadly used as a radical initiator for emulsion polymerization reactions for styrene based polymers such as Acrylonitrile butadiene styrene (ABS). It is also used as a bleach. Sodium persulphate replaces ammonium persulfate in etching mixtures for zinc and printed circuit boards, and is also used for pickling of copper and some other metals. This reagent is suitable for industrial synthesis of products and research applications.
