- Executive summary:
In acute oral toxicity study,dogs were treated with 2-methyl-4-[(2-methylphenyl)diazenyl]aniline in the concentration of 300 mg/kg bw. 50 % mortality was observed at 300 mg/kg bw in treated dog. Therefore,LD50 was considered to be300 mg/kg bw when dog were treated with 2-methyl-4-[(2-methylphenyl)diazenyl]aniline orally.
