Data Sheet

Deepwater Chemicals is a Potassium Iodide manufacturer, offering process development, custom and toll manufacturing of specialty chemicals from lab scale to commercial volumes. We follow cGMP processes and documentation, and have full raw material traceability.

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.
