Key result
Remarks on result:
other: Chemical (CAS no.68991-98-0) ignites only when the flame of bunsen burner having temperature of 950°C is brought in contact with it.Thus it can be concluded that substance is flammable only at high temperature of about 950°C.
Conclusions:
hexasodium 4,4'-{ethene-1,2 -diylbis[(3 -sulfonato-4,1 -phenylene)imino(6 -chloro-1,3,5 -triazine-4,2 -diyl)imino]}bis{6 -[(5 -carbamoyl-1 -ethyl-2 -hydroxy-4 -methyl-6 -oxo-1,6 -dihydropyridin-3 -yl)diazenyl]benzene-1,3 -disulfonate} did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that hexasodium 4,4'-{ethene-1,2 -diylbis[(3 -sulfonato-4,1 -phenylene)imino(6 -chloro-1,3,5 -triazine-4,2 -diyl)imino]}bis{6 -[(5 -carbamoyl-1 -ethyl-2 -hydroxy-4 -methyl-6 -oxo-1,6 -dihydropyridin-3 -yl)diazenyl]benzene-1,3 -disulfonate} is not auto-flammable.
Executive summary:

hexasodium 4,4'-{ethene-1,2 -diylbis[(3 -sulfonato-4,1 -phenylene)imino(6 -chloro-1,3,5 -triazine-4,2 -diyl)imino]}bis{6 -[(5 -carbamoyl-1 -ethyl-2 -hydroxy-4 -methyl-6 -oxo-1,6 -dihydropyridin-3 -yl)diazenyl]benzene-1,3 -disulfonate} did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that hexasodium 4,4'-{ethene-1,2 -diylbis[(3 -sulfonato-4,1 -phenylene)imino(6 -chloro-1,3,5 -triazine-4,2 -diyl)imino]}bis{6 -[(5 -carbamoyl-1 -ethyl-2 -hydroxy-4 -methyl-6 -oxo-1,6 -dihydropyridin-3 -yl)diazenyl]benzene-1,3 -disulfonate} is not auto-flammable.
