INFO
Caesium fluoride, CsF
Caesium fluoride (CsF) is an inorganic compound that forms colorless and highly hygroscopic crystals. This compound is known for its high solubility in water and other polar solvents. It is widely used as a source of fluoride ion in organic synthesis, often serving as a phase-transfer catalyst or as a base. In the realm of solid-state physics and materials science, CsF is studied for its interesting electrical and optical properties. Caesium fluoride is also employed in biochemistry and molecular biology for its ability to disrupt cell walls and facilitate the extraction of cellular materials. However, like other caesium compounds, CsF requires careful handling due to its reactivity and potential corrosive effects. Overexposure can lead to health risks, such as fluoride toxicity and imbalances in cellular ion channels. Thus, proper safety measures must be observed when working with this compound. Overall, CsF is a versatile material with applications ranging from organic synthesis to scientific research.Other name
