Description and Uses
Chloranil: an important intermediate
Chloranil (2,3,5,6-tetrachloro-2,5-cyclohexadiene-1,4-dione), is extensively used as a fungicide, is an intermediate in the synthesis of medicines and pesticides, and is an oxidizing agent used in organic synthesis, particularly for dye intermediates, in China. The annual production of chloranil in recent years, in China, has been about 2000 tonnes. Chloranil is known for its strong oxidizing properties. It can cause oxidative stress and damage to cells by interacting with cysteine residues of some proteins[1-3].
