$ 50.00 Original price was: $ 50.00.$ 47.50Current price is: $ 47.50.
Potassium Iodide USP is a high-purity inorganic halogenated salt that meets the strict quality and purity standards of the United States Pharmacopeia (USP). It appears as white crystalline granules or powder, is odorless, and has a characteristic saline taste. This pharmaceutical-grade compound is valued for its ability to act as a source of iodide ions, its high solubility in water, and its stability when properly stored. It is slightly hygroscopic and may become yellow upon prolonged exposure to air due to liberation of iodine, with light and moisture accelerating decomposition, requiring careful packaging and storage. Potassium Iodide USP is manufactured under current Good Manufacturing Practices (cGMP) and is suitable for human pharmaceutical applications, nutritional supplements, and other uses requiring the highest purity standards.
