What is Potassium Iodide?

Potassium Iodide +99% USP Grade is a stable, non-radioactive iodine compound. It plays a crucial role in blocking radioactive iodine absorption by the thyroid in radiation emergencies, typically involving nuclear power plants. Moreover, it serves as a treatment for hyperthyroidism. It acts as a protective shield for the thyroid gland during specific radiopharmaceutical applications.

How is Potassium Iodide manufactured?

The manufacturing process of Potassium Iodide involves a reaction between potassium hydroxide and iodine. This is followed by a series of purification steps to achieve high purity levels. After the reaction, the compound is dried and crystallized to form white crystals, then finely ground into a powder form. Then thoroughly tested to ensure it meets the purity standard and grade.
