Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The acute oral median lethal dose (LD50) of 5-amino-2-(p-aminoanilino)benzenesulphonic acid in Rat (Wistar ) was estimated to be 3083.33mg/kg bw. This value indicates that 5-amino-2-(p-aminoanilino)benzenesulphonic acid does not exhibits acute toxicity by the oral route as per the criteria of the CLP regulation .
Executive summary:

The acute oral median lethal dose (LD50) of 5-amino-2-(p-aminoanilino)benzenesulphonic acid in Rat (Wistar ) was estimated to be 3083.33mg/kg bw. This value indicates that 5-amino-2-(p-aminoanilino)benzenesulphonic acid does not exhibits acute toxicity by the oral route as per the criteria of the CLP regulation.
