Applicant's summary and conclusion

Interpretation of results:
Category 4 based on GHS criteria
Conclusions:
The lethal concentration (LD50) value for acute oral toxicity test was considered to be 1650 mg/kg bw,when rats were treated with test chemical orally.
Executive summary:

Acute oral toxicity study was performed in rats using test chemical.50% mortality was observed at dose1650 mg/kg bw.In clinical signs observations,changes in urine composition,behavioral excitement and convulsions or effect on seizure threshold were observed.Hence,LD50 value was considered to be1650 mg/kg bw,when rats were treated with test chemical orally.
