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.
Polychlorinated dibenzofurans ( PCDFs) are a family of organic compounds with one or several of the hydrogens in the dibenzofuran structure replaced by chlorines. For example, 2,3,7,8-tetrachlorodibenzofuran (TCDF) has chlorine atoms substituted for each of the hydrogens on the number 2, 3, 7, and 8 carbons (see structure in the upper left ...
Toxic equivalency factor ( TEF) expresses the toxicity of dioxins, furans and PCBs in terms of the most toxic form of dioxin, 2,3,7,8-TCDD. [1] The toxicity of the individual congeners may vary by orders of magnitude . With the TEFs, the toxicity of a mixture of dioxins and dioxin-like compounds can be expressed in a single number – the toxic ...
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.

It is a polycyclic heterocyclic organic compound, since HpCDD contains multiple cyclic structures (two benzene rings connected by a 1,4-dioxin ring) in which two different elements (carbon and oxygen) are members of its rings. [1] HpCDD has molecular formula C 12 HCl 7 O 2 and is an off-white powder, which is insoluble in water.
