Chemical compound / From Wikipedia, the free encyclopedia
Sarin is an extremely toxic synthetic organophosphorus compound. A colourless, odorless liquid, it is used as a chemical weapons due to its extreme potency as a nerve agent. Exposure is lethal even at very low concentrations, where death can occur within one-to-ten minutes after direct inhalation of a lethal dose, due to suffocation from lung muscle paralysis, unless antidotes are quickly administered. People who absorb a non-lethal dose, but do not receive immediate medical treatment, may suffer permanent neurological damage.
