Applicant's summary and conclusion

Interpretation of results:
other: CLP/EU GHS criteria not met, no classification required according to Regulation (EC) No. 1272/2008.
Conclusions:
The oral LD50 value of the test substance in rats was established as ca. 3300 mg/kg body weight.
Executive summary:

The purpose of this study was to assess the toxicity of the test substance when administered to rats in four oral doses. The test substance was administered orally to 10 rats per dose, at 1460, 2220, 3330 and 5000 mg/kg body weight.

17 animals died during the study. Slow respiration, lethargy, depression, coarse tremors in high doses, death overnight to 2 days were observed during the 14 days observational period.

The oral LD50 value of the test substance in rats was established as 3300 mg/kg body weight.
