... was found to be 2,3,5-trichloro-1,4-hydro- quinone. After 60 min of reaction, the toxicity of the intermediates was less than that of 2,3,5-TCP. The toxicity of 3,5-DCP and 2,4-DCP was shown to ... (2, 3-, 2, 4-, 2, 5-, 2, 6-, 3, 4-, and 3,5-DCP) were studied by Minero et al. ( 199 5) to identify reaction by-products.
