Uses
Tetraethylammonium (CAS NO.66-40-0) can be used to alter a compound's solubility by displacing hard acids with this comparatively softer acid. For example, addition of tetraethylammonium bromide to an aqueous solution of a sodium salt may cause it to precipitate from water as the tetraethylammonium salt. The tetraethylammonium salt may also be more lipophilic, dissolving in organic solvents such as chloroform.
In biology, the tetraethylammonium cation is a potassium-selective ion channel blocker. It is used in neurophysiology experiments to block the voltage activated potassium channels involved in the trailing part of the transmission of an action potential along a neuron. Tetraethylammonium is also known to reverse the action of drugs such as tubocurarine, a non-depolarizing blocker. Tetraethylammonium evokes more release of the neurotransmitter, and thus it will reverse the competitive antagonistic block of any drugs belonging to the curare family. Tetraethylammonium salts are used in supercapacitors as electrochemically active species.
