2,3,4,5 - Tetrachloro-nitrobenzene used in the synthesis of intermediate 2,4 - difluoro-3,5 - dichloro-nitrobenzene of pesticides fluorophenyl urea .

Preparation Products :Teflubenzuron-->2,4-Difluoro-3,5-dichloronitrobenzene
Raw materials : Chlorosulfonic acid-->1,2,4-Trichloro-5-nitrobenzene 
 1,2,3,4-Tetrachloro-5-nitrobenzene (CAS NO.879-39-0) is obtained by chlorination of the 2,4,5 - Trichloro-nitrobenzene .
In the reactor, adding a certain amount of 2,4,5 - Trichloro-nitrobenzene and Chlorine acid, which leads to Chlorine, temperature controlled at (60 ± 10)°C, reaction about 10h, the reaction process, thin Layer Chromatography tracking response.After reaction,pouring a large number of ice water after, put it aside, filtration, recrystallization with petroleum ether, after drying, 2,3,4,5 - Tetrachloro-nitrobenzene is obatined.

Questionable carcinogen with experimental neoplastigenic data. When heated to decomposition it emits very toxic fumes of Cl⁻ and NO_x. See also NITRO COMPOUNDS of AROMATIC HYDROCARBONS.
