Tetrachlorobenzene is any of three isomeric chlorobenzenes with the molecular formula C6H2Cl4. They differ by the positions of the chlorine atoms around the ring. Tetrachlorobenzenes are colorless crystalline compounds. [1]

1,2,4,5-Tetrachlorobenzene can be produced by electrophilic halogenation of benzenes and some chlorobenzenes. [2] 1,2,3,4-Tetrachlorobenzene can only be produced by chlorination of 1,3,5-trichlorobenzene.
1,2,4,5-tetrachlorobenzene once was used as intermediates in the production of pesicides, [3] specifically trichlorophenols. This method has been discontinued because it also produced 2,3,7,8-tetrachlorodibenzo-p- dioxin. [1]
