Uses and applications

What the substance is used for, by industry and function

Chemical warfare agent.

Military nerve gas.

Soman (military designation GD) is one of the nerve agents, which are the most toxic of the known chemical warfare agents. It has an odor like camphor or rotting fruit. Exposure to soman can cause death in minutes. A fraction of an ounce (1 to 10 mL) of soman on the skin can be fatal. Nerve agents are chemically similar to organophosphate pesticides and exert their effects by interfering with the normal function of the nervous system.

Pharmacological actions

  • Chemical Warfare Agents
  • Cholinesterase Inhibitors
  • Convulsants

Pharmacology

G-Series Nerve Agent GD is a man-made highly toxic organic phosphate nerve agent that is a clear, colorless liquid that gives off a colorless vapor and smells like camphor or rotting fruit, and is absorbed into the body by inhalation, ingestion, skin contact, or eye contact. GD inhibits acetylcholinesterase, increasing the neurotransmitter acetylcholine at central and peripheral neuronal synapses.

How it is made

Synthesis: DC (methylphosphonyl dichloride), hydrogen fluoride, and pinacolyl alcohol.
