Applicant's summary and conclusion

Interpretation of results:
practically nontoxic
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
LD50 of thiophaniumbromide is >2000 mg/kg bw
Executive summary:

Thiophaniumbromide has been administered as a single dose by gavage to rats using a dosage of 2000 mg/kg bw. No mortality was observed. So the LD50 of thiophaniumbromide can be considered to be larger than 2000 mg/kg bw in the male and female rat.
