Sarin, or
GB, is a colorless, odorless liquid, used as a
chemical weapon owing to its extreme potency as a
nerve agent. It is generally considered as a
weapon of mass destruction. Production and stockpiling of sarin was outlawed as of April 1997 by the
Chemical Weapons Convention of 1993, and it is classified as a
Schedule 1 substance. In June 1994, the UN Special Commission on Iraqi disarmament destroyed the nerve agent sarin under Security Council resolution 687 (1991) concerning the disposal of Iraq's weapons of mass destruction.
