What is a Cesium chloride (CsCl)?

Cesium chloride (CsCl) is an inorganic compound composed of cesium (Cs) and chlorine (Cl), with the chemical formula CsCl. It is typically found as white or colorless crystals and is highly soluble in water. Cesium, an alkali metal, is known for its high reactivity, and cesium chloride exhibits important chemical properties that are useful in various applications. Cesium chloride is commonly used in radiation technology, particularly as a source of radiation in medical and industrial applications. Cesium-137, a radioactive isotope of cesium, is used in radiation therapy and radiation measurement.

In chemical analysis and separation techniques, cesium chloride is employed in methods like density gradient centrifugation, where its high solubility in water allows for the effective separation of substances based on their densities. Cesium ions also play a role in various chemical reactions and semiconductor manufacturing. While cesium chloride has important industrial and scientific uses, it is highly toxic to both humans and the environment, especially when used as a radiation source. Therefore, strict handling and safety protocols are essential.
