Tabun or GA is an extremely toxic synthetic organophosphorus compound.^[1] It is a clear, colorless, and tasteless liquid with a faint fruity odor.^[2] It is classified as a nerve agent because it can fatally interfere with normal functioning of the mammalian nervous system. Its production is strictly controlled and stockpiling outlawed by the Chemical Weapons Convention of 1993. Tabun is the first of the G-series nerve agents along with GB (sarin), GD (soman) and GF (cyclosarin).

Although pure tabun is clear, less-pure tabun may be brown. It is a volatile chemical, although less so than either sarin or soman.^[2]

Tabun can be deactivated chemically using common oxidizing agents such as sodium hypochlorite.^[3]
