VX Chemical formula

Chemical information

Methylphosphonothioic acid S-{2-[bis(1-methylethyl)amino]ethyl} O-ethyl ester.

CAS — 50782-69-9.

Profile

The nerve agents, sarin, soman, tabun, and VX (also referred to as ‘nerve gases’) used in chemical warfare are extremely potent inhibitors of cholinesterase. The effects of poisoning due to these agents, and their treatment, are similar to those for organophosphorus insecticides but as the nerve agents have a much greater intrinsic toxicity the symptoms of poisoning are more severe. Pyridostigmine has been given prophylactically to personnel at risk from exposure to nerve agents.
