GHS Product Identifier: 101.07, Potassium Iodide Technical; 101.24, Potassium Iodide USP; 101.14, Potassium Iodide ACS; 101.08, Potassium Iodide 45% Soln.; 101.09, Potassium Iodide 50% Soln.; 101.84, Potassium Iodide Photo Grade.
Formula Description: Technical:Off white to light brown crystals or granular powder. USP/ACS/Photo:Colorless or white crystals or granular powder; slightly hygroscopic in moist air. Tends to cake during storage. On long exposure to airbecomes yellow due to liberation of iodine. Light and moisture accelerates decomposition. 45% & 50% Solution:Clear colorless to light yellow solution.
Recommended Use: Potassium Iodide is an inorganic halogenated salt that is used inpolymer industry in improving structural properties 1-2. It is a corrosion inhibitor/acid intensifier in oilfield gas production3-4, used in x-ray filmsowing to luminescence properties5, LCD manufacturingas a polarizer6, nylon stabilizer7, trace mineral in animal feeds and/or dietary supplement and food additive8.
