Sarin

Sarin, or GB, is an organophosphorus compound with the formula [(CH3)2CHO]CH3P(O)F. It is a colorless, odorless liquid,[4] used as a chemical weapon owing to its extreme potency as a nerve agent. It has been classified as a weapon of mass destruction[5] in UN Resolution 687. Production and stockpiling of sarin was outlawed by the Chemical Weapons Convention of 1993 where it is classified as a Schedule 1 substance. Even at very low concentrations, sarin can be fatal within one minute after direct ingestion of a lethal dose, due to suffocation from lung muscle paralysis, unless some antidotes, typically atropine or Biperiden and pralidoxime, are quickly administered to a person.[4] People who absorb a non-lethal dose, but do not receive immediate medical treatment, may suffer permanent neurological damage.
