Applicant's summary and conclusion
- Interpretation of results:
- other: Not classified
- Conclusions:
- The lethal concentration (LD50) value for acute oral toxicity test was considered to be >1225 mg/kg/day when deer mice were treated with test chemical orally via gavage over the 3-day test period without killing more than 50% of the test animals.
- Executive summary:
Acute oral toxicity study was done in 2 to 4 deer mice using test chemical .No Mortality was observed at dose 1225 mg/kg/day.Hence,LD50 value was considered to be >1225 mg/kg/day when deer mice were treated with test chemical orally via gavage over the 3-day test period without killing more than 50% of the test animals.
