White Phosphorus
White phosphorus, yellow phosphorus, or simply tetraphosphorus (P4) is an allotrope of phosphorus. It is a translucent waxy solid that quickly yellows in light (due to its photochemical conversion into red phosphorus), and impure white phosphorus is for this reason called yellow phosphorus. White phosphorus is the first allotrope of phosphorus, and in fact the first elementary substance to be discovered that was not known since ancient times. It glows greenish in the dark (when exposed to oxygen) and is highly flammable and pyrophoric (self-igniting) upon contact with air. It is toxic, causing severe liver damage on ingestion and phossy jaw from chronic ingestion or inhalation. The odour of combustion of this form has a characteristic garlic odor, and samples are commonly coated with white " diphosphorus pentoxide", which consists of tetrahedra with oxygen inserted between the phosphorus atoms and at their vertices. White phosphorus is only slightly soluble in water and can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nerve Agent
Nerve agents, sometimes also called nerve gases, are a class of organic chemistry, organic chemicals that disrupt the mechanisms by which nerves transfer messages to organs. The disruption is caused by the blocking of acetylcholinesterase (AChE), an enzyme that catalyzes the breakdown of acetylcholine, a neurotransmitter. Nerve agents are irreversible acetylcholinesterase inhibitors used as poison. Poisoning by a nerve agent leads to constriction of pupils, profuse salivation, convulsions, and involuntary urination and defecation, with the first symptoms appearing in seconds after exposure. Death by asphyxiation or cardiac arrest may follow in minutes due to the loss of the body's control over Respiration (physiology), respiratory and other muscles. Some nerve agents are readily vaporized or aerosolized, and the primary portal of entry into the body is the respiratory system. Nervous agents can also be absorbed through the skin, requiring that those likely to be subjected to su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VX (nerve Agent)
VX is an extremely toxic chemical synthesis, synthetic chemical compound in the organophosphorus compound, organophosphorus class, specifically, a phosphonate, thiophosphonate. In the class of nerve agents, it was developed for military use in chemical warfare after translational science, translation of earlier discoveries of organophosphate toxicity in pesticide research. In its pure form, VX is an oily, relatively Volatility (chemistry), 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 originated from pesticide development work at Imperial Chemical Industries (ICI). It was developed further at Porton Down 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 class ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mustard Gas
Mustard gas or sulfur mustard are names commonly used for the organosulfur compound, organosulfur chemical compound bis(2-chloroethyl) sulfide, which has the chemical structure S(CH2CH2Cl)2, as well as other Chemical species, species. In the wider sense, compounds with the substituents are known as ''sulfur mustards'' or ''nitrogen mustards'', respectively, where X = Cl or Br. Such compounds are potent alkylating agents, making mustard gas acutely and severely toxic. Mustard gas is a carcinogen. There is no preventative agent against mustard gas, with protection depending entirely on skin and airways protection, and no antidote exists for mustard poisoning. Also known as mustard agents, this family of compounds comprises infamous cytotoxicity, cytotoxins and blister agents with a long history of use as chemical weapons. The name ''mustard gas'' is technically incorrect; the substances, when Dispersion (chemistry), dispersed, are often not gases but a fine mist of liquid droplet ...

Bigeye Bomb
The BLU-80/B BIGEYE bomb was a developmental U.S. air-launched binary chemical weapon. The BIGEYE was a class glide bomb with a radar altimeter fuze intended to disperse the binary generated nerve agent VX, made in flight from the non-lethal chemical components " QL" and sulfur only after aircraft release. The BLU-80-B was designed under the auspices of the U.S. Navy as a safe chemical weapons alternative in response to chemical weapons (CW) threats from the USSR and other actors. BIGEYE was a genuine tri-service program led by the U.S. Navy with significant U.S. Army and U.S. Air Force participation. Initially approved in the 1950s, the program persisted into the 1990s. Background As the stockpile of U.S. unitary (live agent) chemical weapons began to show troubling leakage, the Department of Defense (DoD) became acutely aware of the safety hazard to military personnel and public backlash this could generate. It is now known that the Soviets experienced the same and likely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M687
The M687 was an American 155 mm binary sarin chemical artillery shell. The design was standardized in 1976 and production began on December 16, 1987 at Pine Bluff Arsenal, Pine Bluff, Arkansas. Production was halted three years later, following the 1990 Chemical Weapons Accord between the United States and the USSR, and the dismantling of existing stocks began in November 1997 at Hawthorne Army Depot, Nevada. America's remaining stocks were stored at the Deseret Chemical Depot, Utah, and the Umatilla Chemical Depot (Umatilla County, Oregon). The shell contained two canisters separated by a rupture disk. The compartments were filled with two liquid precursor chemicals for sarin (GB2): methylphosphonyl difluoride (denominated DF) and a mixture of isopropyl alcohol and isopropyl amine (denominated OPA) is in a second canister. The isopropyl amine binds the hydrogen fluoride generated during the chemical reaction. When the shell was fired the force of the acceleration would ca ...

Methylphosphonic Difluoride
Methylphosphonyl difluoride (DF), also known as EA-1251 or difluoro, is a chemical weapon precursor. Its chemical formula is CH3POF2. It is a Schedule 1 substance under the Chemical Weapons Convention. It is used for production of sarin and soman as a component of binary chemical weapons; an example is the M687 artillery shell, where it is used together with a mixture of isopropyl alcohol and isopropyl amine, producing sarin. Preparation Methylphosphonyl difluoride can be prepared by reacting methylphosphonyl dichloride with hydrogen fluoride (HF) or sodium fluoride (NaF). Safety Methylphosphonyl difluoride is both reactive and corrosive. It is absorbed through skin and causes burns and mild nerve agent symptoms. It reacts with water, producing HF fumes and methylphosphonic acid Methylphosphonic acid is an organophosphorus compound with the chemical formula CH3P(O)(OH)2.

Incapacitating Agent
Incapacitating agent is a chemical or biological agent which renders a person unable to harm themselves or others, regardless of consciousness. Lethal agents are primarily intended to kill, but incapacitating agents can also kill if administered in a potent enough dose, or in certain scenarios. The term "incapacitation," when used in a general sense, is not equivalent to the term "disability" as used in occupational medicine and denotes the inability to perform a task because of a quantifiable physical or mental impairment. In this sense, any of the chemical warfare agents may incapacitate a victim; however, by the military definition of this type of agent, incapacitation refers to impairments that are temporary and nonlethal. Thus, riot-control agents are incapacitating because they cause temporary loss of vision due to blepharospasm, but they are not considered military incapacitants because the loss of vision does not last long. Although incapacitation may result from physio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
