Cesium propionate, CAS 38869-24-8

Organic cesium carboxylate salts, such as cesium formate, acetate, propionate, oxalate, lactate, cesium citrate and tartrate are increasingly being selected as useful additives for a variety of industrial applications such as in the hydrocarbon recovery areas. Cesium propionate is a useful synthetic chemical reagent which exhibits reactivity properties that have been dubbed the “cesium effect”. It is e well suited for organic SN2 displacement on primary and secondary halides, mesylates, tosylates, etc. In SN2 displacement reactions the bigger and more electropositive cesium is known to offer better yields compared to lithium, sodium, or potassium analogues. In solar cells, cesium propionate is used as a more hydrophobic additive in cesium lead halide perovskites; where the propionate substitutes the commonly used acetate, chloride, nitrate, phosphate, or sulfate, etc. Cesium propionate is also used as a liquid crystal precursor, epoxide-cleaving agent, ion exchange reagent, cesium catalyst, precursor for cesium lead halide perovskites, cesium-based catalysts, synthetic reagent, aqueous brines used in well servicing fluids, precursor for cesium doped catalysts. In dopant and ion exchange chemistries, cesium propionate is most useful for intercalating clays, clays, zeolites, molecular sieves as well as modifying their hydroxyl surface moieties.
