 Soman was discovered by Richard Kuhn in Germany in 1944, and represented the last wartime nerve agent discovery (GF was not found until 1949). Soman was given the identifier GD post-war (GC was already in medical use) when the information relating to soman was recovered by the Soviet Union from its hiding place in a mine. The 3D crystal structure of soman complexed with acetylcholinesterase was determined by Millard et al. (1999) and can be seen at Proteopedia 1som.

 Soman (CAS NO.96-64-0) can be thickened for use as a chemical spray using an acryloid copolymer. It can also be deployed as a binary chemical weapon; its precursor chemicals are methylphosphonyl difluoride and a mixture of pinacolyl alcohol and an amine.

A deadly experimental poison by inhalation, skin contact, subcutaneous, intravenous, intramuscular, and intraperitoneal routes. An extremely toxic military nerve gas. Mutation data reported. When heated to decomposition it emits very toxic fumes of F⁻ and PO_x.

 Soman (CAS NO.96-64-0) is also called 1,2,2-Trimethylpropyl methylphosphonofluoridate ; 1,2,2-Trimethylpropylester kyseliny methylfluorfosfonove ; 1-Methyl-2,2-dimethylpropylmethylphosphonofluoridate ; 2-Butanol, 3,3-dimethyl-, methylphosphonofluoridate ; 3,3-Dimethyl-2-butyl methylphosphonofluoridate ; 3,3-Dimethyl-n-but-2-yl methylphosphonofluoridate ; BRN 1928737 ; CCRIS 3417 ; EA 1210 ; GD ; HSDB 6764 ; Methyl pinacolyl phosphonofluoridate ; Methylphosphonofluoridic acid 1,2,2-trimethylpropyl ester ; Phosphonofluoridic acid, methyl-, 1,2,2-trimethylpropyl ester ; Pynacolyl methylfluorophosphonate ; T.2107 ; Zoman . Soman (CAS NO.96-64-0) is colorless liquid, odorless to fruity. It is hydrolyzed by water, rapidly hydrolyzed by dilute aqueous sodium hydroxide. Water alone removes Fluoride atom producing nontoxic acid. Acidic conditions produce hydrogen fluoride; alkaline conditions produce isopropyl alcohol and polymers. When heated to decomposition or reacted with steam, Soman emits very toxic fumes of fluorides and oxides of phosphorus. Slightly corrosive to steel. Health Hazard Median lethal dose (mg-min/m3): 2500 by skin (vapor) or 350 (liquid); 35 inhaled. Median incapacitating dose: 25 inhaled. Eye/skin toxicity: Very high. Rate of action: Very rapid. Physiological action: Cessation of breath-death may follow. Detoxification rate: Low, essentially cumulative. (ANSER)
