Key result
Test procedure:
other: not specified

other: Chemical (CAS no.503155-49-5 ) 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:
2 -Naphthalenesulfonic acid, 7 -amino-4 -hydroxy-3 -[[2 -methoxy-5 -methyl-4 -[[2 -(sulfooxy)ethyl]sulfonyl] phenyl]azo]-8 -[[2 -sulfo-4 -[[2 -(sulfooxy)ethyl]sulfonyl]phenyl]azo]-, tetrasodium salt 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 -Naphthalenesulfonic acid, 7 -amino-4 -hydroxy-3 -[[2 -methoxy-5 -methyl-4 -[[2 -(sulfooxy)ethyl]sulfonyl] phenyl]azo]-8 -[[2 -sulfo-4 -[[2 -(sulfooxy)ethyl]sulfonyl]phenyl]azo]-, tetrasodium salt is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 2 -Naphthalenesulfonic acid, 7 -amino-4 -hydroxy-3 -[[2 -methoxy-5 -methyl-4 -[[2 -(sulfooxy)ethyl]sulfonyl] phenyl]azo]-8 -[[2 -sulfo-4 -[[2 -(sulfooxy)ethyl]sulfonyl]phenyl]azo]-, tetrasodium salt was considered non-flammable.
Executive summary:

2 -Naphthalenesulfonic acid, 7 -amino-4 -hydroxy-3 -[[2 -methoxy-5 -methyl-4 -[[2 -(sulfooxy)ethyl]sulfonyl] phenyl]azo]-8 -[[2 -sulfo-4 -[[2 -(sulfooxy)ethyl]sulfonyl]phenyl]azo]-, tetrasodium salt does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it.
