GHS Product Identifier: 113.04, Sodium Iodide Tech; 113.05, Sodium Iodide 57% Soln.; 113.14, Sodium Iodide USP; 113.15, Sodium Iodide High Purity; 113.25, Sodium Iodide Pure; 113.34, Sodium Iodide ACS.

Formula Description: Technical:White to light yellow crystalline powder. USP/High Purity/Pure:Colorless, odorless crystals or white crystalline powder. Deliquescent in moist air and develops a brown tint upon decomposition. Very soluble in water, freely soluble in alcohol and acetone. ACS:White powder; odorless; slowly becomes brown in air; deliquescent; saline, somewhat bitter taste. Soluble in water alcohol and acetone. 57% Solution:Clear, colorless to light brown liquid.

Recommended Use: Sodium Iodide is an inorganic halogenated salt that is highly soluble. It finds medical applications as a thyroid symporter 1in cancer treatment. Sodium Iodide is also used as a scintillation detector and high efficiency for detection gamma rays. NaIis a common reagent for organic synthesis reactions and in the weather modification industry
