摘要:
Metabolism in vivo of 2,4,3',4'-tetrachlorobiphenyl (TCB) was further studied using male Wistar rats. When the extract of feces of rats given TCB with chloroform was methylated and applied to gas chromatography (GC)-mass spectrometry (MS), a new metabolite was detected. The structure of this new metabolite was 4-hydroxy-2,5,3'4'-TCB based on both its retention time in GC and comparison of the mass spectrum with that of the synthetic sample. 4-Hydroxy-2,5,3',4'-TCB was assumed to be formed via a 4,5-oxide intermediate followed by NIH-shift of a chlorine atom at 4-position.
