Description of key information

2-aminonaphthalene-1,5-disulfonic acid does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that 2-aminonaphthalene-1,5-disulfonic acid is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 2-aminonaphthalene-1,5-disulfonic acid was considered non-flammable for chemical safety assessment.
