Conclusions:
The acute oral LD50 value was considered to be >5000 mg/kg bw, when rats were treated with 2,2'-[(3,3'-dichloro[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[N-(2,4-dimethylphenyl)-3-oxobutyramide] (CAS no: 5102-83-0) via oral route.
Executive summary:

Acute oral toxicity study of 2,2'-[(3,3'-dichloro[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[N-(2,4-dimethylphenyl)-3-oxobutyramide] (CAS no: 5102-83-0) was conducted in rats at the concentration of 5000 mg/kg bw. No mortality was observed in treated rats at 5000 mg/kg bw. Therefore, LD50 was considered to be >5000 mg/kg bw, when rats were treated with 2,2'-[(3,3'-dichloro[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[N-(2,4-dimethylphenyl)-3-oxobutyramide] via oral route.
