Beschreibung
Cyclosarin was the fourth of the G-series of nerve agents to be
described following the development of tabun (GA), the first
G-agent to be discovered in 1938. Cyclosarin was given the
designation GF, reflective of the order in which it was
discovered.
As with the other G-agents, after learning of its properties
the German Ministry of Defense began studying cyclosarin
along with the United States and United Kingdom following
World War II. Cyclosarin, unlike other G-agents, was not
selected for mass production by any nations at that time
possibly due to the cost of reagents required for cyclosarin
production. After the Gulf War, it was discovered that Iraq
had stockpiled G-agents including cyclosarin. Rockets containing
both sarin and cyclosarin were found and destroyed
by the US forces at the Khamisiyah weapons depot resulting
in exposure to these two agents. One possible reason why
Iraq stockpiled cyclosarin despite the fact that no other
nation had done so, is that the precursor chemicals for sarin
production, but not cyclosarin were embargoed making it
a more desirable selection. Additionally, cyclosarin is the
most persistent of the G-agents potentially making it
a greater threat.
In 1997, the Chemical Weapons Convention (CWC) was
enacted that banned the production, stockpiling, and use of
chemical weapons (including cyclosarin) and called for the
destruction of existing chemical weapons stockpiles. The CWC
is administered by the Organisation for the Prohibition of
Chemical Weapons, of which nearly all world nations are
a part.
Chemische Eigenschaften
Cyclosarin (GF) is a liquid nerve agent/organ-
ophosphate containing fluoride. GF is a colorless liquid.
The odor is variously described as nondescript, sweet, fruit-
like. Odor threshold is about 12 milligram per cubic meter.
Verwenden
Cyclosarin is a synthetic organophosphate (OP) compound
used in chemical warfare and terrorism.
Definition
A highly toxic colourlessliquid, C
7H
14FO
2P; r.d. 1.13; m.p.–30°C; b.p. 239°C. it is a fluorinatedorganophosphorus compound,(fluoromethylphosphoryl)oxycyclohexane.Cyclosarin was discovered in1949 and belongs to the G-series ofnerve agents (GF).
Allgemeine Beschreibung
Colorless liquid, odorless to fruity.
Air & Water Reaktionen
Likely hydrolyzed by water, rapidly hydrolyzed by dilute aqueous sodium hydroxide.
Reaktivität anzeigen
Acidic conditions produce hydrogen fluoride; alkaline conditions produce isopropyl alcohol and polymers. When heated to decomposition or reacted with steam, cyclohexyl methylphosphonofluoridate emits very toxic fumes of fluorides and oxides of phosphorus. Slightly corrosive to steel. Hydrolyzed by water.
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. (ANSER)
mögliche Exposition
A quick-acting and lethal cholinester-
ase inhibitor and casualty agent. Females appear to be more
susceptible to nerve agent effects. Small percentages of
general population have genetic traits that may increase
susceptibility.

Inkompatibilitäten
Fairly stable. Cyclo-sarin (GF) is hydro-
lyzed by water; rapidly hydrolyzed in the presence of heat
and alkalies; by dilute solution of aqueous sodium hydrox-
ide. Contact with alkaline conditions produce isopropyl
alcohol and polymer substances. Contact with acid condi-
tions produce HF; alkaline conditions produce isopropyl
alcohol and polymers. Reasonably stable when stored in
steel at normal temperatures; slightly corrosive to steel
when heated.
