Description

Cesium Fluoride (CsF) is an inorganic compound composed of cesium and fluorine, widely utilized in organic synthesis and materials science due to its exceptional reactivity and solubility. With a molecular formula of CsF and CAS number 13400-13-0, this high-purity reagent is available as a white crystalline powder, hygroscopic in nature, and must be stored under inert conditions to maintain stability. Cesium fluoride is prized for its strong basicity and nucleophilic fluoride source, making it indispensable in fluorination reactions, phase-transfer catalysis, and as a desilylating agent. Its low lattice energy enhances solubility in polar aprotic solvents, facilitating efficient reaction kinetics. Ideal for researchers and industrial chemists, our CsF meets stringent quality standards for applications requiring precise chemical control.

Application

Cesium fluoride is extensively used as a fluorinating agent in organic synthesis, particularly in nucleophilic aromatic substitution and desilylation reactions. It serves as a catalyst in phase-transfer reactions due to its high solubility in organic media. Additionally, CsF is employed in the preparation of anhydrous hydrogen fluoride and as a component in specialty glasses and optical materials.
