O-Ethyl Methylphosphonothioic Acid
''O''-Ethyl methylphosphonothioic acid (EMPTA) is an organophosphate compound. A dual-use chemical, it has constructive uses in the synthesis of pesticides and pharmaceuticals, and it is also a precursor in the synthesis of nerve agents such as Agent VM and Agent VX. The detection of EMPTA is cited as a major influence in the United States' 1998 decision to destroy the Al-Shifa pharmaceutical factory The Al-Shifa (الشفاء, Arabic for "healing") pharmaceutical factory in Khartoum North, Sudan, was constructed between 1992 and 1996 with components imported from Germany, India, Italy, Sweden, Switzerland, Thailand and the United States. ... in Sudan.

Organophosphate Compound
In organic chemistry, organophosphates (also known as phosphate esters, or OPEs) are a class of organophosphorus compounds with the general structure , a central phosphate molecule with alkyl or aromatic substituents. They can be considered as esters of phosphoric acid. Like most functional groups, organophosphates occur in a diverse range of forms, with important examples including key biomolecules such as DNA, RNA and ATP, as well as many insecticides, herbicides, nerve agents and flame retardants. OPEs have been widely used in various products as flame retardants, plasticizers, and performance additives to engine oil. The popularity of OPEs as flame retardants came as a substitution for the highly regulated brominated flame retardants. The low cost of production and compatibility to diverse polymers made OPEs to be widely used in industry including textile, furniture, electronics as plasticizers and flame retardants. These compounds are added to the final product ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VM (nerve Agent)
VM (Edemo) is a "V-series" nerve agent closely related to the better-known VX nerve agent. Like most of the agents in the V-series (with the exception of VX), VM has not been extensively studied outside of military science. Little is known about this chemical compound other than its chemical formula. It is commonly theorized that the so-called "second-generation" V series agents came from a Cold War era Russian chemical weapons development program. They may have been developed sometime between 1950 and 1990. They have similar lethal dose levels to VX (between 10 and 50 mg) and have similar symptoms and method of action to other nerve agents that act on cholinesterase. The treatment remains the same, but the window for effectively treating second generation V series seizures is shorter. In addition to the standard seizures, some of the second generation V series agents are known to cause coma A coma is a deep state of prolonged unconsciousness in which a person ...

VX (nerve Agent)
VX is an extremely toxic synthetic chemical compound in the organophosphorus class, specifically, a thiophosphonate. In the class of nerve agents, it was developed for military use in chemical warfare after translation of earlier discoveries of organophosphate toxicity in pesticide research. In recent years, VX was found to be the agent used in the assassination of Kim Jong-nam. In its pure form, VX is an oily, relatively non-volatile liquid that is amber-like in colour. Because of its low volatility, VX persists in environments where it is dispersed. VX, short for "venomous agent X", is one of the best known of the V nerve agents and was first discovered at Porton Down by Ranajit Ghosh in England during the early 1950s based on research first done by Gerhard Schrader, a chemist working for IG Farben in Germany during the 1930s. It is now one of a broader V-series of agents which are classified as nerve agents and have been used as a chemical weapon in various recor ...

Al-Shifa Pharmaceutical Factory
The Al-Shifa (الشفاء, Arabic for "healing") pharmaceutical factory in Khartoum North, Sudan, was constructed between 1992 and 1996 with components imported from Germany, India, Italy, Sweden, Switzerland, Thailand and the United States. It was opened on 12 July 1997 and bombed by the United States on 20 August 1998. The industrial complex was composed of four buildings. It was the largest pharmaceutical factory in Khartoum and employed over 300 workers, producing medicine both for human and veterinary use. The factory was destroyed in 1998 by a missile attack launched by the United States government, killing one employee and wounding eleven. The U.S. government claimed that the factory was used for the processing of VX nerve agent and that the owners of the plant had ties to the terrorist group al-Qaeda. These justifications for the bombing were disputed by the owners of the plant, the Sudanese government, and other governments. American officials later acknowledged "t ...
