摘要

The metabolic fate of 4-bromoaniline (4-BrA) was investigated following intraperitoneal administration to the rat at 50 mg kg(-1), using high-performance liquid chromatography/time-of-flight tandem mass spectrometry (HPLC/TOF-MS/MS). Up to five metabolites were detected in urine that correspond to isomeric pentose conjugates (possibly ribosides) of a hydroxysulphate of 4-BrA. This identification is supported by further studies where the water used in the reversed-phase solvent system was replaced with deuterated water in order to confirm that the number of exchangeable protons present in the metabolites was consistent with the proposed structures.Copyright 2002 John Wiley & Sons, Ltd.
