Cesium hydroxide (Cat No.:M055138) is a highly reactive and strong base, composed of cesium and hydroxide ions. It typically appears as a white, hygroscopic solid that is highly soluble in water, producing a heat-releasing, exothermic reaction. Cesium hydroxide is one of the strongest bases known and is used in various chemical applications, including as a catalyst and in organic synthesis to promote certain reactions. Its strong alkalinity makes it effective for saponification, the process of making soap from fats and lye.
