Potassium Iodide (CAS: 7681-11-0) is used as a raw material for organic compounds and pharmaceuticals, food additive, feed additive, is also used as analytical reagents. Potassium Iodide is used medically to prevent and treat goiter (large neck disease) and preoperative preparations for hyperthyroidism. Potassium Iodide can also be used for photo-making and so on. Potassium iodide is found in seaweed. Some important applications of this compound involve its use in pharmaceuticals and as a source of iodine in food,especially in animal and poultry feed. Potassium iodide is added to table salt to provide iodine in human food. Another major use is in making photographic emulsions. In analytical chemistry, Potassium Iodide is used in iodometric titration with starch indicator to analyze dissolved oxygen, dissolved chlorine, sulfide, and other analytes in water.
