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.
Contact of the ammonium iodide with the naked eyes of a living being can cause irritation in the eyes. The toxic and irritating fumes of the hydrogen iodide, iodine, and oxides of nitrogen may result in the fire. The compound may sublime into the fire and then condense on the cold surfaces.
Ammonium iodide is the chemical compound NH4I. It is used in photographic chemicals and some medications. It can be prepared by the action of hydroiodic acid on ammonia. It is easily soluble in water, from which it crystallizes in cubes.
Ammonium sulfide is sold commercially as a liquid that is primarily composed of ammonium bisulfide, NH4HS. Ammonium sulfide is used in photographic developers, in the manufacture of textiles, and to produce a dark patina on brasses and bronzes
