Conclusions:
The acute oral LD50 value was considered to be 5000 mg/kg bw, when rats were treated with the given test chemical orally.
Executive summary:

In a acute oral toxicity study, rats were treated with the given test chemical at the concentration of 5000 mg/kg bw orally. Animals were observed for mortality. 50% mortality was observed in treated rats at 5000 mg/kg bw. Therefore, The acute oral LD50 value was considered to be 5000 mg/kg bw, when rats were treated with the given test chemical orally.
