Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The acute oral median lethal dose (LD50) of 5-nitro-o-anisisdine in rat was found to be 2315.143 mg/kg of body weight.
Executive summary:

The acute oral median lethal dose (LD50) of 5-nitro-o-anisisdine in rat was found to be 2315.143 mg/kg of body weight. This value indicates that 5 -nitro-o-anisidine does not exhibit acute toxicity by the oral route.
