Metabolic studies on pentachloronitrobenzene (PCNB) in rats

Abstract

The metabolism of PCNB in rats was studied. Metabolites isolated from rat excreta and identified were: N-acetyl-S-(pentachlorophenyl)cysteine, pentachlorothiophenol, pentachlorothioanisole, 2,3,4,5-tetrachlorothiophenol, 2,3,4,5-tetrachlorothioanisole, 2,3,4,6- and/or 2,3,5,6-tetrachloro-thiophenol and -thioanisole, 1,4-bis(methylthio)tetrachlorobenzene, 1,4-dimercapto-tetrachlorobenzene and/or 4-methylthio-tetrachlorothiophenol, pentachlorophenol, pentachloroanisole, 2,3,4,5-tetrachlorophenol, 2,3,4,5-tetrachloroanisole, 2,3,4,6- and/or 2,3,5,6-tetrachloro-phenol and -anisole, pentachlorobenzene, 2,3,4,5-tetrachloronitrobenzene, pentachloroaniline and 2,3,4,5-tetrachloroaniline.
