China and the United States are the leading exporters of sodium iodide, accounting for the largest shares of global shipments, while Germany, Japan, and South Korea are the top importers, driven by pharmaceutical and radiopharmaceutical manufacturing demand. Trade volumes have remained relatively stable over the past three years, with modest growth in Asian imports coinciding with upward pressure on sodium iodide prices amid tightening supply chain logistics and raw material constraints.
Sodium iodide is a white, crystalline, odorless solid that is highly soluble in water and hygroscopic under ambient conditions; it melts at 661 °C and decomposes before boiling. It is an inorganic ionic compound composed of sodium cations and iodide anions. Sodium iodide serves primarily as a source of iodide ions in organic synthesis—especially in nucleophilic substitution reactions—and as a precursor to other iodine-containing compounds. Its principal applications are in the pharmaceutical industry for radiopharmaceuticals (e.g., iodine-131 labeled agents) and as a reagent or intermediate in the production of contrast media, disinfectants, and certain agrochemicals.
Used as iodometric reagent
It is colorless cubic crystal or white crystalline powder. It is odorless with salty taste bitter. It is easily soluble in water, soluble in methanol, ethanol, acetone, glycerol, liquid ammonia and liquid sulfur dioxide. The aqueous solution was slightly alkaline.
