Key result
Remarks on result:
other: The chemical CAS no. 35642-64-9 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:
7-[[2-[(aminocarbonyl)amino]-4-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]phenyl]azo]naphthalene-1,3,6-trisulphonic acid did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 7-[[2-[(aminocarbonyl)amino]-4-[(4-amino-6-chloro-1 ,3,5-triazin -2-yl)amino]phenyl]azo]naphthalene-1,3,6-trisulphonic acid is not auto-flammable.
Executive summary:

7-[[2-[(aminocarbonyl)amino]-4-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]phenyl]azo]naphthalene-1,3,6-trisulphonic acid did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 7-[[2-[(aminocarbonyl)amino]-4-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]phenyl] azo]naphthalene-1,3,6-trisulphonic acid is not auto-flammable.
