Tetraethylammonium iodide


Tetraethylammonium iodide is a quaternary ammonium compound with the chemical formula C8H20N+I−. It has been used as the source of tetraethylammonium ions in pharmacological and physiological studies, but is also used in organic chemical synthesis.

Chemistry

Preparation

Tetraethylammonium iodide is commercially available, but can be prepared by the reaction between triethylamine and ethyl iodide.

Structure

The crystal structure of tetraethylammonium iodide has been determined. The crystal structure is a distorted wurtzite lattice. At the nitrogen atom, the coordination is a flattened tetrahedron. The N−C−C angle is slightly larger than the tetrahedral angle.

Synthetic applications

Examples include:
LD50: 35 mg/kg ; 56 mg/kg
