Additional information
The disposition of p-[14C]nitroaniline (PNA) was studied in male F-344 rats following oral and/or intravenous (iv) administration. The gastrointestinal absorption of PNA was near complete and was not affected by dose in the range studied (2-100 mumol/kg). Following either oral or intravenous administration, PNA was rapidly distributed throughout the tissues and showed no marked affinity for any particular tissue. The clearance of [14C]PNA-derived radioactivity from various tissues was rapid and followed a two-component decay curve. The whole body half-life of PNA was approximately 1 hr. Within 3 days clearance of PNA-derived radioactivity from the body was almost complete. [14C]PNA was rapidly cleared by metabolism to nine metabolites which were excreted primarily in the urine and to a lesser extent in feces. Most (56%) of the urinary radioactivity was in the form of sulfate conjugates of two metabolites of PNA; the excretion of unmetabolized PNA was minimal (less than 3%). Biliary excretion of [14C]PNA was significant, however, much of this PNA-derived radioactivity underwent enterohepatic circulation and was subsequently excreted in urine. The results of this study indicate that, if metabolism is a detoxification process, the rapid metabolism and excretion of this compound minimize the likelihood of significant toxicity from repeated exposure to PNA beyond that predicted by data from acute or short-term exposures.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
