Key result
Remarks on result:
other: The given chemical (CAS no. 93964-07-9) 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:
N-(2-ethylhexyl)-1-[[2-methyl-4-[(4-methylphenyl)azo]phenyl]azo]naphthalen-2-amine did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that N-(2-ethylhexyl)-1-[[2-methyl-4-[(4-methylphenyl)azo]phenyl]azo]naphthalen-2-amine is not auto-flammable.
Executive summary:

N-(2-ethylhexyl)-1-[[2-methyl-4-[(4-methylphenyl)azo]phenyl]azo]naphthalen-2-amine did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that N-(2-ethylhexyl)-1-[[2-methyl-4-[(4-methylphenyl)azo]phenyl]azo]naphthalen-2-amine is not auto-flammable.
