Applicant's summary and conclusion

Interpretation of results:
Category 4 based on GHS criteria
Conclusions:
The acute oral LD50 value was considered to be 1000 mg/kg bw, when rats was treated with the given test chemical via oral route.
Executive summary:

Acute oral toxicity study of the given test chemical was conducted in rats at the concentration of 1000 mg/kg bw.

Animals were observed for mortality. 50% mortality was observed at 1000 mg/kg bw in treated animals.

Hence, the LD50 value was considered to be 1000 mg/kg bw, when rats was treated with the given test chemical via oral route.
