Description_x000D_ General description_x000D_ Tetramethylammonium chloride is a quaternary ammonium salt commonly used as a catalyst due to its thermal stability and also tolerance towards strong aqueous bases or nucleophiles._x000D_ Application_x000D_ Tetramethylammonium chloride along with N-hydroxyphthalimide and xanthone may be used as an efficient chloride catalytic system for the aerobic oxidation of hydrocarbons to form the corresponding oxygenated compounds. It may also be used as a phase transfer catalyst for the synthesis of aryl fluorides via selective chloride/fluoride exchange reaction of activated aryl chlorides with potassium fluoride in solid-liquid phase._x000D_ Packaging_x000D_ 100, 500 g in poly bottle_x000D_ 5 g in glass bottle
