Anwendungen & Verwendung
Verwenden
3-Chloro-5-(trifluoromethyl)pyridine (3CTFP) is a pyridinium salt that is a byproduct of the production of chlorofluorocarbons. It is used to reduce the level of chlorine in water, and it can be used as a pesticide. 3CTFP is also an anion that can be reduced to form the chloride ion. 3CTFP reacts with nucleophiles such as ammonia or amines, which leads to nucleophilic substitution reactions. This reaction can be reversed by adding acid. The product from this reaction is ammonia gas.
