Potassium Iodide (CAS 7681-11-0) – Wholesale & Research Grade
Potassium iodide is a metal iodide salt with a K(+) counterion. It is a scavenger of hydroxyl radicals. It has a role as a radical scavenger, an expectorant and a NMR chemical shift reference compound. It contains an iodide.
Research Context
Potassium iodide, often referred to as KI or iodide of potassium, is a versatile compound widely utilized in various research applications due to its unique chemical properties. One significant area of research involves its use in radiological emergencies, where it serves as a protective agent against thyroid cancer induced by radioactive iodine exposure. By saturating the thyroid gland with non-radioactive iodine, potassium iodide effectively blocks the uptake of harmful isotopes, underscoring its importance in nuclear safety protocols.
Mechanism of Action
The mechanism of action of potassium iodide is primarily based on its ability to compete with radioactive iodine for absorption in the thyroid gland. When administered prior to or shortly after exposure to radioactive iodine, KI saturates the thyroid with stable iodine, thus mitigating the risk of thyroidal uptake of radioactive isotopes. This protective action not only aids in emergency situations but is also a valuable tool in thyroid-related studies and treatments.
Solubility and Storage Advice
Potassium iodide is highly soluble in water, making it easy to incorporate into various aqueous solutions for experimental purposes. However, it is crucial to store KI in a cool, dry place, away from light and moisture to prevent degradation. Containers should be tightly sealed to maintain the compound's stability and efficacy over time. Proper storage conditions ensure that potassium iodide retains its properties for research and therapeutic applications.
Future Research Directions
Future research on potassium iodide is likely to explore its role in the treatment of thyroid disorders beyond radiological exposure. Investigations into its potential antioxidant properties and applications in other medical fields, such as dermatology and pulmonology, are gaining interest. Additionally, the synthesis of novel iodide compounds may open new avenues for enhancing the efficacy of potassium iodide in various therapeutic contexts, warranting further exploration and innovation in this area.
