The formation of glutathione (GSH) conjugate in the detoxification of [Ring-UL-14C]-2,4-dinitrobromobenzene (DNBB) was investigated using rat liver cytosolic fraction. The mercapturic acid conjugate in rats was also studied by collection of urine of rats dosed with radioactive DNBB by intraperitoneal
