Dibenzofuran is a heterocyclic organic compound with the chemical structure shown at right. It is an aromatic compound that has two benzene rings fused to a central furan ring. All the numbered carbon atoms have a hydrogen atom bonded to each of them.
2,3,7,8-Tetrachlorodibenzofuran (TCDF) is a polychlorinated dibenzofuran with a chemical formula of C 12 H 4 Cl 4 O. TCDF is part of the chlorinated benzofuran (CDF) family that contains between 1 and 8 chlorine atoms attached to the parent dibenzofuran ring system. The CDF family includes 135 compounds, of which only a few have been studied.
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 ...
Dibenzofuran, an analog with a second fused benzene ring. Furan, an analog without the fused benzene ring. Indole, an analog with a nitrogen instead of the oxygen atom. Benzothiophene, an analog with a sulfur instead of the oxygen atom. Isobenzofuran, the isomer with oxygen in the adjacent position. Aurone; Thunberginol F

The fusion of two benzene rings gives rise to a third large family of organic compounds. Analogs of the previously mentioned heterocycles for this third family of compounds are acridine, dibenzothiophene, carbazole, and dibenzofuran, respectively. Heterocyclic organic compounds can be usefully classified based on their electronic structure.
Berberine, a plant compound traditionally used in herbal medicine, is today commonly stocked on the shelves of health food stores and pharmacies as a supplement. Beyond weight loss, berberine also ...
PCDFs are derivatives of dibenzofuran. There are 135 isomers; 10 have dioxin-like properties. Polychlorinated biphenyls (PCBs), derived from biphenyl, of which 12 are "dioxin-like". Under certain conditions PCBs may form dibenzofurans through partial oxidation. Polybrominated analogs of the above classes may have similar effects.
