| Application: | Cesium hydroxide monohydrate can be used: • As a catalyst to prepare unsymmetrical Bis-allyl ethers via dimerization of Baylis-Hillman adducts. • As a dopant to fabricate vanadium oxide thin films as a hole extraction layer for perovskite solar cells. • As an initiator for ring opening polymerization of monosubstituted oxiranes. • As a promoter to synthesize secondary amines via chemoselective N-alkylation. |
| Features and Benefits: | • As a strong base ≥99.5% CsOH serves as an effective catalyst in organic reactions, enhancing reaction rates and selectivity without the risk of impurities affecting the outcomes. • ≥99.5% CsOH is used in the synthesis of various cesium compounds, ensuring that contaminants do not interfere with chemical reactions, leading to higher yields and purity of the final products. |
| General description: | Cesium hydroxide is a strong base that can be used in organic synthesis, as a catalyst, and as an intermediate in the production of cesium compounds. |
