Applications Cesium fluoride is a fluorination agent for halide exchange reactions. It is a versatile base in organic synthesis and can be used in e.g. in polymerisation reactions or in brazing fluxes.
Safety and handling Because of its hygroscopicity cesium fluoride should be stored in tightly closed containers. Handling in moist air should be avoided. Safe handling requires the safety precautions typical for inorganic fluorides. Thus, eyes or skin should not be exposed to cesium fluoride, otherwise severe
irritation may result. Ingestion must be avoided because of the toxicity of fluoride.
