Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
Since LD50> 2000 mg/kg, there is no classification required.
Executive summary:

The single oral administration of the test substance (ZK 39211) to male and female rats at a dose of 2000 mg/kg was tolerated without any compound-related clinical or macroscopic pathological signs. The acute oral toxicity of ZK 39211 in rats is above 2000 mg/kg body weight.
