Other findings:
Rats treated with 4-fluoroaniline showed cyanosis between days 1 and 4 and irregular respiration on day 1; mean body weights of treated rats
decreased on day 2 and were significantly lower than those of control on days 4, 8, 15 and 16

Applicant's summary and conclusion

Interpretation of results:
Toxicity Category IV
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Oral toxicity (TDLo) of 4-fluoroaniline to rat was examined at dose concentration of 600 mg/kg of body weight.
Executive summary:

The potential for neurotoxicity after a single oral dose of 4-fluoroaniline (4-FA), given to rats, was investigated at or near the lethal dosage level. Hindlimb paralysis was found clinical observation, with the maximum incidence of 100% in 4-FA groups.

Oral toxicity (TDLo) of 4-fluoroaniline to rat was examined at dose concentration of 600 mg/kg of body weight.
