Sodium Iodide


  • A white, crystalline salt with chemical formula NaI and used in the field of radiation detection, therapy of iodine deficiency & in the Finkelstein reaction as a reactant.
  • It is obtained as a product between reaction of iodine and sodium hydroxide.
  • In polymerase chain reactions, NaI helpful in conversion of an alkyl chloride into an alkyl iodide. This relies on the insolubility of sodium chloride in acetone to generate the reaction.
  • The principle of Scintillation detector is the use of a special material which  scintillates when radiation interacts with it. The most common type of material is a type of salt called sodium-iodide.
