Applicant's summary and conclusion

Interpretation of results:
other: Not classified
Conclusions:
Acute oral toxicity dose (LD50) value was considered to be 3530 mg/kg bw, when rats were treated with the given test chemical via oral route.
Executive summary:

The acute oral toxicity study was conducted by using the given test chemical in 20 rats at the dose concentration of 1.25 - 10 g/kg via oral route. The given test chemical was dissolved in Agar/Tween. The animals were weighed and dosed after a one-week observation. Rats were observed daily for 7 to 14 days, during which time food and water were allowed ad libitum; in some instances, animals were sacrificed and autopsied for gross pathology. 50% mortality was observed at 3530 mg/kg bw. Clinical signs was observed such as ataxia.

Hence, the LD50 value was considered to be 3530 mg/kg bw, when rats were treated with the given test chemical via oral route.
