Key result
Test procedure:
other: Not specified
Remarks on result:
other: 4,5-dihydro-5-oxo-4-[[4-[[2-(sulphooxy)ethyl]sulphonyl]phenyl]azo]-1-(4-sulphophenyl)-1H-pyrazole-3-carboxylic acid not ignited when the flame of bunsen burner having temperature of approximately 950°C was brought in contact with it.
Interpretation of results:
other: non flammable
Conclusions:
4,5 -dihydro-5 -oxo-4 -[[4 -[[2 -(sulphooxy)ethyl]sulphonyl]phenyl]azo]-1 -(4 -sulphophenyl)-1H-pyrazole-3 -carboxylic 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 4,5 -dihydro-5 -oxo-4 -[[4 -[[2 -(sulphooxy)ethyl]sulphonyl]phenyl]azo]-1 -(4 -sulphophenyl)-1H-pyrazole-3 -carboxylic acid is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 4,5 -dihydro-5 -oxo-4 -[[4 -[[2 -(sulphooxy)ethyl]sulphonyl]phenyl]azo]-1 -(4 -sulphophenyl)-1H-pyrazole-3 -carboxylic acid was considered non-flammable for chemical safety assessment.
Executive summary:

4,5 -dihydro-5 -oxo-4 -[[4 -[[2 -(sulphooxy)ethyl]sulphonyl]phenyl]azo]-1 -(4 -sulphophenyl)-1H-pyrazole-3 -carboxylic 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 4,5 -dihydro-5 -oxo-4 -[[4 -[[2 -(sulphooxy)ethyl]sulphonyl]phenyl]azo]-1 -(4 -sulphophenyl)-1H-pyrazole-3 -carboxylic acid is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 4,5 -dihydro-5 -oxo-4 -[[4 -[[2 -(sulphooxy)ethyl]sulphonyl]phenyl]azo]-1 -(4 -sulphophenyl)-1H-pyrazole-3 -carboxylic acid was considered non-flammable for chemical safety assessment.
