Applicant's summary and conclusion

Interpretation of results:
Category 5 based on GHS criteria
Conclusions:
The lethal concentration (LD50) value for acute oral toxicity test was considered to be 7460 mg/kg bw ,when rats were treated with 5-[(4,6-dichloro-1,3,5-triazin-2-yl)amino]-4-hydroxy-3-(phenylazo)naphthalene-2,7-disulphonic acid (6522-86-7) orally.
Executive summary:

Acute oral toxicity study was done in rats using test material 5-[(4,6-dichloro-1,3,5-triazin-2-yl)amino]-4-hydroxy-3-(phenylazo)naphthalene-2,7-disulphonic acid (6522-86-7).50% mortality was observed at dose 7460 mg/kg bw. Hence,LD50 value was considered to be 7460 mg/kg bw,when rats were treated with 5-[(4,6-dichloro-1,3,5-triazin-2-yl)amino]-4-hydroxy-3-(phenylazo)naphthalene-2,7-disulphonic acid (6522-86-7) orally.
