Sources/Uses

A ganglion blocking agent; [Merck Index] In common with tetraethylammonium chloride and tetraethylammonium iodide, TEAB has been used as a source of tetraethylammonium ions for numerous clinical and pharmacological studies, which are covered in more detail under the entry for Tetraethylammonium. Briefly, TEAB has been explored clinically for its ganglionic blocking properties, although it is now essentially obsolete as a drug, and it is still used in physiological research for its ability to block K+ channels in various tissues."
