GV is the name of a Soviet nerve agent , which is structurally similar to the neurotoxin soman . The US Department of Defense and NATO gave this warfare agent the designation GV (G for Germany ; V for English viscous "tough, viscous").
Isomerism
GV has a stereocenter on the phosphorus atom, so there are two enantiomers , one has an ( R ) configuration, the other has an ( S ) configuration. The manufacturing processes described provide the racemic GV, i.e. a 1: 1 mixture of ( R ) - (dimethylamido) fluorophosphoric acid 2- N ', N ' - (dimethylaminoethyl) ester (left) and ( S ) - (dimethylamido) fluorophosphoric acid- 2- N ′, N ′ - (dimethylaminoethyl) ester (right):
Protective measures
Even the smallest amounts of GM are fatal. The target is the entire body. Therefore, only a full-body protective suit and a protective mask offer sufficient protection. Oxime tablets can be taken before a warfare agent is used. During the weeks of post-treatment, trying to Obidoxime the acetylcholinesterase regenerate.
Oxidizing agents and alkaline solutions can be used for decontamination , as the hydrolysis of nerve agents is accelerated in an alkaline environment. Chlorinated lime for insensitive surfaces and sodium carbonate solutions for sensitive objects have also proven their worth .
