1, Potassium iodide is used as a raw material for organic compounds and pharmaceuticals.
2, Potassium iodide CAS 7681-11-0 is used medically to prevent and treat goiter (large neck disease) and preoperative preparations for hyperthyroidism.
3, Potassium iodide CAS 7681-11-0 can also be used as an expectorant.
4, Potassium iodide can also be used for photo-making and so on.
1. Medical Use:
Thyroid Protection: KI is used to protect the thyroid gland from radioactive iodine in the event of a nuclear accident or exposure to radiation.
Expectorant: It is sometimes used in cough syrups to help thin mucus in the respiratory tract.
2. Nutritional supplements:
KI is used as a source of iodine in dietary supplements and in iodized salt to prevent thyroid problems caused by iodine deficiency.
3. Laboratory Reagents:
In the laboratory, potassium iodide is used in various chemical reactions and as a reagent in analytical chemistry.
4. Photography:
KI is used in some photographic processes, particularly in the preparation of certain types of photographic emulsions.
5. Industrial Application:
It is used in the production of iodine and in some chemical syntheses.
6. Preservatives:
KI can be used in some antiseptic formulations due to its antimicrobial properties.

Stored in a ventilated and dry warehouse.
1. Container: Potassium iodide is hygroscopic, please store it in a sealed container to prevent moisture absorption.
2. Temperature: Store in a cool, dry place away from direct sunlight and heat. Ideal storage temperature is usually between 15°C and 30°C (59°F and 86°F).
3. Humidity: Because potassium iodide absorbs moisture from the air, it is important to store it in a low humidity environment. Using a desiccant in the storage container can help reduce humidity.
4. Label: Clearly label the container with the contents and storage date to ensure proper identification and use.
5. Safety Precautions: Store it away from incompatible substances (such as strong acids and oxidizing agents) to prevent any potential reactions.
When transporting Potassium Iodide (KI), certain precautions must be taken to ensure safety and adherence to regulations. Here are some things to keep in mind during transportation:
1. Packaging:
Use suitable strong, moisture-proof packaging. Ensure containers are tightly sealed to prevent leakage and contamination.
2. Tag:
Packaging should be clearly labeled with the contents, including the chemical name and any associated hazard information. Comply with all applicable hazardous materials labeling regulations.
3.Temperature control:
If possible, store potassium iodide in a temperature-controlled environment and avoid extreme heat or cold, as this may affect the integrity of the product.
4. Avoid moisture:
As KI is hygroscopic, ensure that the packaging is moisture-proof to prevent water absorption during transportation.
5. Processing:
Handle the material with care to avoid spillage or breakage. If necessary, use appropriate personal protective equipment (PPE) such as gloves and goggles.
6. Transportation Regulations:
Comply with local, national and international regulations regarding the transport of chemicals. This may include specific requirements for documentation, labelling and handling.
7. Emergency Procedure:
Know the emergency procedures in case of spills or exposures during transport. Prepare a spill kit and first aid supplies.
