Applicant's summary and conclusion

Interpretation of results:
non flammable
Remarks:
Migrated information
Conclusions:
It can be concluded that 3-amino-4-methoxybenzenesulphonic acid is flammable only at high temperature of about 950 deg C. However since such high temperatures are not found under normal circumstances of transportation and use, 3-amino-4-methoxybenzenesulphonic acid was considered non-flammable for chemical safety assessment.
Executive summary:

From the experimental values of flammability, 3-amino-4-methoxybenzenesulphonic acid ignited when the flame of Bunsen burner having temperature of 950 deg C was brought in contact with it. Thus it can be concluded that 3-amino-4-methoxybenzenesulphonic acid is flammable only at high temperature of about 950 deg C. However since such high temperatures are not found under normal circumstances of transportation and use, 3-amino-4-methoxybenzenesulphonic acid was considered non-flammable for chemical safety assessment.
