Used as a catalyst or reagent in organic synthesis, particularly in fluorination reactions where a soluble and stable cesium source is required. Enhances reaction efficiency in nucleophilic substitution and cross-coupling processes. Employed in the preparation of fluorinated pharmaceuticals and fine chemicals due to its ability to promote carbon-fluorine bond formation. Also utilized in electrochemical applications and as a component in specialty electrolytes for high-performance batteries. Its trifluoroacetate anion contributes to solubility in polar organic solvents, making it suitable for homogeneous reaction conditions.
