Usage

Description

Cesium hydroxide hydrate (99.9%-CS) is a high-purity chemical compound with the chemical formula CsOH·H2O. It is a strong base and is commonly used in various chemical reactions and processes due to its unique properties.

Uses

Used in Chemical Synthesis:
Cesium hydroxide hydrate (99.9%-CS) is used as a catalyst for the conversion of alcohols, substituted anilines, and heterocyclic amines. In the presence of N-methyl-2-pyrrolidone (NMP), these compounds undergo an addition reaction to phenylacetylene, leading to the formation of functionalized enol ethers and enamines. This application is particularly useful in the synthesis of complex organic molecules and pharmaceuticals.
Used in Chemoselective N-Alkylation:
Cesium hydroxide hydrate (99.9%-CS) is also utilized in the chemoselective N-alkylation of secondary amines with alkyl halides. This reaction is essential in the production of various organic compounds, including pharmaceuticals, agrochemicals, and other specialty chemicals. The use of cesium hydroxide hydrate as a catalyst enhances the selectivity and efficiency of the N-alkylation process, resulting in fewer by-products and a higher yield of the desired product.
