Executive summary:

The acute oral toxicity of the test substance was investigated in young adult Wistar rats according to OECD guideline 401. The test article was dissolved in arachidis oil and given orally by means of a stomach tube in a dose of 2000 mg/kg body weight to 5 male and 5 female animals. At frequent intervals at the day of application and twice a day in the following 14 days, the rats were observed for any signs of reaction. The surviving rats were sacrified at the end of the observation period and a macroscopic postmortem examination was performed on all rats. The LD50 was >2000 mg/kg for male and female rats.
