Description of key information

3-acetamido-5-amino-4-hydroxybenzenesulphonic acid did not catch fire on being exposed to air at room temperature of 30 degC and atmospheric pressure of 975 hPa. This indicates that 3-acetamido-5-amino-4-hydroxybenzenesulphonic acid is not auto-flammable.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

From the experimental values of flammability, 3-acetamido-5-amino-4-hydroxybenzenesulphonic acid ignited when the flame of bunsen burner having temperature of 950°C was brought in contact with it. Thus, it can be concluded that this substance is flammable only at high temperature of about 950°C. However, since such high temperatures are not found under normal circumstances of transportation and use, 3-acetamido-5-amino-4- hydroxy benzenesulphonic acid was considered non-flammable for chemical safety assessment.
