Key result
Remarks on result:
other: 1-[(2, 4-dimethylphenyl) diazenyl]-2-naphthol 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:
1-[(2, 4-dimethylphenyl) diazenyl]-2-naphthol did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 1-[(2, 4-dimethylphenyl) diazenyl] -2- naphthol is not auto-flammable.
Executive summary:

1 -[(2, 4 -dimethylphenyl) diazenyl]-2 -naphthol did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that   1 -[(2, 4 -dimethylphenyl) diazenyl]-2 -naphthol is not auto-flammable.
