Infobox references. 2,3,7,8-Tetrachlorodibenzo-p-dioxin ( TCDD) is a polychlorinated dibenzo -p- dioxin (sometimes shortened, though inaccurately, to simply 'dioxin') [3] with the chemical formula C 12 H 4 Cl 4 O 2. Pure TCDD is a colorless solid with no distinguishable odor at room temperature.
The 2,4,5-T used was contaminated with 2,3,7,8-tetrachlorodibenzodioxin (TCDD), an extremely toxic dioxin compound. During the Vietnam war, between 1962 and 1971, the United States military sprayed 20,000,000 U.S. gallons (76,000,000 L) of chemical herbicides and defoliants in Vietnam, eastern Laos and parts of Cambodia, as part of Operation ...
TCDD as defined here, is a single compound 2,3,7,8-tetrachlorodibenzo-p-dioxin, and the sources given are common to many related compounds. The sole sources of pure TCDD are accidents (Seveso) or deliberate poisonings as described. Please check Dioxins and dioxin-like compounds, and add the necessary sources there.
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Octachlorodibenzodioxin (can be abbreviated as OCDD or OctaCDD) is one of polychlorinated dibenzodioxins (PCDDs). Its toxicity is similar to TCDD, but it is about 3000 times weaker. [1] It is one of the dominant dioxin congeners ...

2,3,7,8-Tetrachlorodibenzodioxin (TCDD) is always a contaminant in this compound's production. Several accidents releasing many kilograms of TCDD have been reported. The reaction between 2,4,5-trichlorophenol and formaldehyde is exothermic. If the reaction occurs without adequate cooling, TCDD is produced in significant quantities as a ...
