Caesium fluoride or cesium fluoride is an inorganic compound usually encountered as a hygroscopic white solid. It is used in organic synthesis as a source of the fluoride anion.Caesium has the lowest electronegativity of all non-radioactive elements and fluorine has the highest electronegativity of all elements.aesium fluoride can be prepared by the reaction of caesium hydroxide (CsOH) with hydrofluoric acid (HF). The resulting salt can then be purified by recrystallization.
Clostridium difficile (C. difficile) is a type of bacteria that is associated with diarrhea resulting from antibiotic use. C. difficile testing and C. difficile toxin tests identify the presence of these bacteria and detect the toxins produced by them.
