Overview

Cesium chloride is widely used in isopycnic centrifugation for separating various types of DNA. It is a reagent in analytical chemistry, where it is used to identify ions by the color and morphology of the precipitate. When enriched in radioisotopes, such as 137CsCl or 131CsCl, cesium chloride is used in nuclear medicine applications such as treatment of cancer and diagnosis of myocardial infarction.
