FOLLOWING THE ORAL OR IP ADMIN OF 4,4'-DINITROBIPHENYL TO GUINEA PIGS, 4,4'-DIACETYLBENZIDINE (4,4'-DIACETYLAMINOBIPHENYL) WAS EXCRETED IN THE URINE. THE METABOLISM OF 4,4'-DINITROBIPHENYL IN THE RAT WAS CONSIDERABLY SLOWER THAN IN THE GUINEA PIG. 3-CHLORO-4-AMINO-4'-NITROBIPHENYL & 3-CHLORO-4-ACETAMIDO-4'-NITROBIPHENYL WERE FOUND IN THE URINE OF RATS BUT NOT OF GUINEA PIGS. APPARENTLY, IN THE RAT HALOGENATION OCCURS IN A METABOLIC PATHWAY FOR THE METABOLITES OF 4,4'-DINITROBIPHENYL, 4-AMINO-4'-NITROBIPHENYL & 4-ACETAMIDO-4'-NITROBIPHENYL.
