2,3,7,8-Tetrachlorodibenzo-p-dioxin

3. 2,3,7,8-Tetrachlorodibenzo-p-dioxin

Heard of Agent Orange? 2,3,7,8-Tetrachlorodibenzo-p-dioxin was the contaminant in Agent Orange. That's a bastard chemical. Agent Orange was created to cause defoliation of dense areas in Vietnam, but this contaminant led to severe prenatal deformities and skin lesions.

2,3,7,8-Tetrachlorodibenzo-p-dioxin is a polychlorinated dibenzo-p-dioxin with the chemical formula C ₁₂H ₄Cl ₄O ₂. TCDD is a colorless solid with no distinguishable odor at room temperature. Wikipedia

2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a polychlorinated dibenzo p-dioxin(sometimes shortened, though inaccurately, to simply "dioxin") with the chemical formula C
12H
4Cl
4O
2. TCDD is a colorless solid with no distinguishable odor at room temperature. It is usually formed as a side product in organic synthesis and burning of organic materials.

TCDD is the most potent compound (congener) of its series (polychlorinated dibenzodioxins, known as PCDDs or simply dioxins) and became known as a contaminant in Agent Orange. a herbicide used in the Vietnam War. TCDD was released into the environment in the seveso disaster. It is a persistent environmental contaminant usually present in a complex mixture of Dioxin like compounds, and is a carcinogen.

 The Expert Group of the World Health Organization considered developmental toxicity as the most pertinent risk of dioxins to human beings. Because people are usually exposed simultaneously to a number of dioxin-like chemicals, a more detailed account is given at dioxins and dioxin like compounds.

Betrachotoxin

1. Betrachotoxin  Betrachoxin is most dangerous chemical in the world. It was named by scientists John W Daly and Burnhard Witkop. who separated  the potent toxic alkaloids fraction and determined its chemical properties.  Batrachotoxin is an extremely potent cardiotoxic and neurotoxic steroidal alkaloid found in certain species of frogs, melyrid beetles, and birds. Batrachotoxin was derived from the Greek word βάτραχος bátrachos "frog". Formula: C 31 H 42 N 2 O 6 LD 50   (median dose):  2 μg/kg; (mouse, sub-cutaneous) Molar mass:   538.68 g·mol −1 Main   hazards:  Highly toxic Chemspider:  10310314 Pubchem   CID:  31958 Density: 1.304 gm/ml. The "poison dart" (or "poison arrow") frog does not produce batrachotoxin itself. It is believed that the frogs get the poison from eating beetles or other insects in their native habitat. Frogs raised in captivity do not produce batrachotoxin, and thus may be handled without risk.

Tabun

4. Tabun One of the first nerve agent discovered , this liquid is known for a fruity odor and can be sprayed as a mist that causes convulsions and paralysis. Tabun itself is not extremely deadly, but the success of this chemical compound in war led to the development of deadlier toxins like ricin and soman. Iraqi soldiers used Tabun in the final days of the Iron/iraq to kill thousands of Iranians . Tabun or GA is an extremely toxic chemical substance. It is a clear, colorless, and tasteless liquid with a faint fruity odor. It is classified as a nerve agent because it fatally interferes with normal functioning of the mammalian nervous system. Formula :  C 5 H 11 N 2 O 2 P Density :  1.09 g/cm³ Boiling point :  240 °C Melting point :  −50 °C (−58 °F; 223 K) Main hazards :  Highly toxic. Fires involving this chemical may result in the formation of hydrogen cyanide Appearance :  Colorless to brown liquid. Molar mass : 162.13 g/mol Vapor pressure : 0.07 mm*Hg

VX

2. VX One of the first chemical WMDs, researchers initially produced VX for retail sale in the 1950s as a Pesticide . Thankfully, your likelihood of coming in contact with VX is extremely low - the world's stockpiles have been destroyed, including the United States' main stockpile in anniston ,AL . VX is the top 2 most dangerous chemical in the world. VX  chemical name  is O-ethyl S-diisopropylaminomethyl methylphosphonothiolate , is hard to detect. It is a clear, tasteless and colourless liquid with a consistency something like engine oil. VX is an extremely toxic synthetic chemical compound in the organophosphorus class, specifically, a thiophosphonate. Boiling point :  298 °C Formula :  C 11 H 26 NO 2 PS Melting point :  −51 °C (−60 °F; 222 K) LD 50   (median dose) :  7 µg/kg (intravenous, rat) Log p :  2.047 Vapor Pressure :  0.09 Pa Molar mass : 267.37 g/mol Density : 1.0083 g/cm.
