Pinacolyl esters

Soman (or GD, EA 1210, Zoman, PFMP, A-255, systematic name: O-pinacolyl methylphosphonofluoridate) is an extremely toxic chemical substance. It is a nerve agent, interfering with normal functioning of the mammalian nervous system by inhibiting the enzyme cholinesterase. It is an inhibitor of both acetylcholinesterase and butyrylcholinesterase. As a chemical weapon, it is classified as a weapon of mass destruction by the United Nations according to UN Resolution 687. Its production is strictly controlled, and stockpiling is outlawed by the Chemical Weapons Convention of 1993 where it is classif

EA-2613 is an extremely toxic organophosphate nerve agent. It is an extremely potent acetylcholinesterase inhibitor that is resistant to atropine and oxime treatment.

Chlorosoman is a chlorine analog of soman. It is a highly toxic organophosphorus compound and is used as the precursor substance for soman nerve agent. Its physical properties are estimated. Soman is insoluble in water, with a boiling point of 223 °C and a melting point of -27 °C. Chlorosoman is at least 2.5 times less toxic than soman.
