GP, or 2,2-Dimethylcyclopentyl methylphosphonofluoridate, is a chiral, military grade toxicity organophosphorus compound, is a compound formulated in C8H16FO2P. GP forms a colorless and unscented liquid in pure form, in the impure form it is a colored liquid predominating several shades of amber by its degree of purity, with probable fruity smell coming from its closed chain alkoxy. GP has a boiling point of 222.49 degrees Celsius, being vacuum distilled, GP having more than double the vapor pressure of Ciclosarin, presented a vapor pressure of 0.094213 mmHg at 25 degrees Celsius, GP has an evaporation rate, evaporating 30 times slower than sarin, evaporating approximately 8 to 10 times slower than water.
GP is a persistent G-series persistent, similar to that of Ciclosarin, GP is extremely toxic, having high liposolubility by several means of exposure, especially percutaneously, GP is a nervous agent more toxic than Sarin and GH. GP is slightly soluble in water, persisting in it for days, it is speculated that it has a persistence higher than Ciclosarin and Soman in water due to its lower solubility, at high temperatures GP has a higher dissociation rate than GF. GP has high solubility in common organic solvents, as well as a good solubility rate in fats, oils, fatty acids, soap, lipids, triglycerides and the like. It has a persistence similar to that of Soman and Ciclosarin in environments, because it has a closed carbon chain and its persistence is considerably greater in any environment, but due to its greater evaporation than Ciclosarin, GP is thought to have lower persistence due to decomposition by air, GP as well as other G-series agent, is a non-persistent neurotoxic agent, exhibiting a low persistence in general, in normal environments, in normal environments and normal conditions, G-series agents are degraded within one week.
GP is disseminated by common means of dissemination, it is disseminated through common means, mines, chemical munitions, explosives, sprays, airplanes, sprayers, by missiles and rockets, pyrotechnic grenades, extinguishers, thermal grenades, propellants, cylinders, aerosols, nebulizers, humidifiers , polymer solutions (Lucite), piping tunnels, closed sites, closed complexes, atomizers and others, as well as other organophosphorous agents, GP is destroyed by bleach powder (alkaline components), satisfactory decontamination kits for G agents -series.
