It is a colorless, odorless liquid, used as a chemical weapon owing to its extreme potency as a nerve agent. It has been classified as a weapon of mass destruction 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. Production and structure Sarin is a chiral molecule (typically racemic), with four substituents attached to the tetrahedral phosphorus center. The SP form (shown) is the more active enantiomer due to its greater binding to acetylcholinesterase. It is prepared from methylphosphonyl difluoride and a mixture of isopropyl alcohol. CH3P(O)F2 + (CH3)2CHOH รข†' [(CH3)2CHO]CH3P(O)F + HF Isopropylamine is added to neutralize the ...
