Applicant's summary and conclusion

Interpretation of results:
other: not classified
Conclusions:
The lethal concentration (LD50) value for acute oral toxicity test was considered to be >5000 mg/kg bw,when rats were treated with 2,7 Naphthalendisulfonic acid (3861-73-2) orally.
Executive summary:

Acute oral toxicity study was performed in rats using test material 2,7 Naphthalendisulfonic acid(3861-73-2).No mortality was observed at dose 5000 mg/kg bw.Clinical signs like changes in urine composition, behavioral excitement ,dermatitis and other signs after systemic exposure were observed. Hence,LD50 value was considered to be >5000 mg/kg bw,when rats were treated with 2,7 Naphthalendisulfonic acid(3861-73-2) orally.
