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 3-amino-4-methoxybenzenesulphonic acid in mouse(Nude CD-1) in 72hr study was estimated to be 3566.666748047 mg/kgbw.
Executive summary:

The acute oral median lethal dose (LD50) of 3-amino-4-methoxybenzenesulphonic acid in mouse(Nude CD-1) in72 hr study was estimated to be 3566.666748047 mg/kgbw. Thus considering the CLP Criteria for classification of the substance, it is concluded that 3-amino-4-methoxy benzene sulphonic acid could not exhibit acute toxicity in Nude CD-1 by the oral route.
