Cesium carbonate, 99% (metals basis), Thermo Scientific Chemicals

Description

Catalyst in ethylene oxide polymerization, in coating spatter-free welding of steel in CO2, and in oxide cathodes

Cesium carbonate is the precursor for other cesium compounds. It acts as a base in sensitive organic reactions. Suzuki, Heck and Sonogashira synthesis are some of the important reactions involving cesium carbonate. It finds use in solar cells as it increases the power conversion efficiency of cells through the transfer of electrons. It is also used in the production of special optical glasses, petroleum catalytic additives, special ceramics, and in sulfuric acid industry. It is useful in the N-alkylation (of sulfonamides, beta-lactams, indoles, heterocycles, and several sensitive nitrogen compounds), carbamination of amines, carbonylation of alcohols, and aerobic oxidation of alcohols into carbonyl compounds without over oxidations.
