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.

(13)C metabolic MRI using hyperpolarized (13)C-bicarbonate enables preclinical detection of pH. To improve signal-to-noise ratio, experimental procedures were refined, and the influence of pH, buffer capacity, temperature, and field strength were investigated. Bicarbonate preparation was investigated. Bicarbonate was prepared and
