Key result
Remarks on result:
other: The given chemical (CAS no. 80019-42-7) 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:
Tetrasodium 3-[[5-[[4-chloro-6-[[3-[[2-(sulphonatooxy)ethyl]sulphonyl]phenyl]amino] -1,3,5-triazin-2-yl] amino] -2-sulphonatophenyl]azo]-4-hydroxy-5-[(1-oxopropyl)amino]naphthalene-2,7-disulphonate (CAS no. 80019-42-7) did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that Tetrasodium 3-[[5-[[4-chloro-6-[[3-[[2-(sulphonatooxy)ethyl]sulphonyl]phenyl]amino] -1,3,5-triazin-2-yl] amino] -2-sulphonatophenyl]azo]-4-hydroxy-5-[(1-oxopropyl)amino]naphthalene-2,7-disulphonate (CAS no. 80019-42-7) is not auto-flammable.
Executive summary:

Tetrasodium 3-[[5-[[4-chloro-6-[[3-[[2-(sulphonatooxy)ethyl]sulphonyl]phenyl]amino] -1,3,5-triazin-2-yl] amino]-2-sulphonatophenyl]azo] -4-hydroxy-5-[(1-oxopropyl)amino]naphthalene-2,7-disulphonate (CAS no. 80019-42-7) did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that Tetrasodium 3-[[5-[[4-chloro-6-[[3-[[2-(sulphonatooxy)ethyl]sulphonyl]phenyl] amino]-1,3,5-triazin-2-yl] amino] -2-sulphonatophenyl]azo]-4-hydroxy-5-[(1-oxopropyl)amino]naphthalene-2,7-disulphonate (CAS no. 80019-42-7) is not auto-flammable.
