General description

Potassium iodide is an inorganic sodium salt. It is used as a source of iodide in organic synthesis. In the presence of oxidizing agents, it iodinates aromatic hydrocarbons and organothallium compounds. It is also used as a reagent for the cleavage of some ethers in the presence of acid.

Application

Potassium iodide can be used as a reducing agent for the reduction of graphene oxide in the presence of hydrochloric acid. It is also used as a dopant in the preparation of solid polymer electrolytes for energy devices.

Features and Benefits

  • Increased efficiency – Eliminates time and effort of loosening hardened powders      
  • Safety – Eliminates tools of force used to break up clumps
  • Ecology – Reduces waste as it does not stick to the packaging
  • Economy – Faster preparation and solvation increase productivity and reduce costs      
  • Assured Quality – Excellent, expert-tested quality with no anti-caking agents     
  • Flexible volumes – Available from research amounts to scale-up quantities
