Potassium Iodide
SINOBIO
281511000
Potassium iodide (CAS No. 7681-11-0) is an important inorganic compound. The following is a detailed introduction:
Chinese Name: Potassium Iodide
English Name: Potassium Iodide
Chemical Formula: KI
Molecular Weight: 166.0028 g/mol
CAS No.: 7681-11-0
EINECS No.: 231-442-4 (Some sources show 231-659-4, which may differ due to different database updates or classification standards)
Appearance: Colorless or white cubic crystals, sometimes in powder form
Odor: Odorless
Taste: Strong bitter and salty taste
Density: 3.13 g/cm³
Melting Point: 681°C
Boiling Point: 1330°C
Solubility: Easily soluble in water, soluble in ethanol, methanol, acetone, glycerol, and liquid ammonia; slightly soluble in ether. Its aqueous solution is neutral or slightly alkaline.
1. Stability: Potassium iodide is relatively stable in dry air, but it readily absorbs moisture in humid air and may be oxidized, releasing free iodine and gradually turning yellow. Light and moisture accelerate its decomposition.
2. Reactivity: Potassium iodide can react with oxidizing agents to produce elemental iodine. For example, it reacts with chlorine gas to produce potassium chloride and elemental iodine.
Potassium iodide is commonly known as gray iodine. Chemical formula KI. Molecular weight 166.00. Colorless or white cubic crystals. The taste is salty and bitter. Slightly deliquescent in humid air, easily oxidized when exposed to air, precipitates iodine and gradually turns yellow. Light and moisture can accelerate its decomposition. Specific gravity 3.13. Melting point 681 ºC. Boiling point 1330 ºC. Easy to dissolve in water, soluble in ethanol, glycerol, and liquid slightly soluble in ether. Its aqueous solution is neutral or slightly alkaline, and water-soluble Chemicalbook solution can dissolve iodine, generating triiodide ions (I3-). Its aqueous solution is also prone to oxidation and yellowing, making it easier when acidic. Adding alkali can prevent it. Obtained by the interaction of hydroiodic acid and potassium bicarbonate.
Used as an analytical reagent and raw material for producing iodides and dyes, as well as as as a photosensitive emulsifier and food additive. In medicine, it is used to prevent and treat goiter (large neck disease), as well as for preoperative preparation of hyperthyroidism. In addition, it can also be used as expectorant and diuretic drugs.
Potassium iodide (KI) is a chemical compound composed of potassium and iodine. It is a crystalline salt that is colorless and odorless. Potassium iodide has various applications, both in the medical field and in industrial processes. Its most well-known use is in the prevention of thyroid damage caused by exposure to radioactive iodine.

Nuclear Emergency Preparedness: In the event of a nuclear accident or release of radioactive iodine, potassium iodide tablets are distributed to populations at risk to be taken as a preventive measure.
Iodine Deficiency Disorders: Potassium iodide is used in iodine supplementation programs to prevent iodine deficiency disorders, particularly in areas where there is insufficient iodine in the diet.
Photography: It is used in the photographic industry as a component of photographic chemicals.
Pharmaceuticals: Potassium iodide is employed in certain pharmaceutical formulations, such as expectorants and antifungal medications.
Analytical Chemistry: Potassium iodide is used in analytical chemistry for various titrations and reactions.
Laboratory Reagent: It serves as a reagent in laboratories for various chemical reactions and experiments.
Food Industry: In some cases, potassium iodide is used as a stabilizer and anti-caking agent in the food industry.
* Potassium iodide is an important drug for treating thyroid diseases (such as goiter and hyperthyroidism). It can promote the synthesis and release of thyroid hormones, thereby regulating thyroid function.
* In radiation emergency situations, potassium iodide can be used to protect the thyroid gland from damage caused by radioactive iodine.
* Potassium iodide is also used as an expectorant and diuretic.
* Potassium iodide is a permitted iodine fortifier for food. It can be added to table salt to prevent iodine deficiency disorders (such as goiter).
* The use of potassium iodide in infant formula is strictly limited to ensure safety and effectiveness.
* Potassium iodide also has wide applications in photolithography, organic synthesis, and analytical chemistry.
* It can also be used as a raw material in photosensitive emulsions, soaps, and lithography.
-It should be stored in a cool, ventilated, light-proof warehouse.
-When transporting, it should be protected from rain and sunshine.
-When loading and unloading, it should be carried gently and placed lightly, and vibration and impact are strictly prohibited.
Packing: 25kg/drum. 25kg/bag. We provide customized package for different quantity.
Shipping: by express DHL,FEDEX,TNT......or as your requirement.
Payment: T/T,western union,moneygram or as your requirement.
