Key result

Remarks on result:

other: 2-[[4-[bis(2-hydroxyethyl)amino]-o-tolyl]azo]-5-nitrobenzonitrile ignites only when the flame of bunsen burner having temp of 950°C is brought in contact with it.Thus it can be concluded that substance is flammable only at high temp of about 950°C.

Conclusions:

2-[[4-[bis(2-hydroxyethyl)amino]-o-tolyl]azo]-5-nitrobenzonitrile (CAS no. 12236-25-8) did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 2-[[4-[bis(2-hydroxyethyl)amino]-o-tolyl]azo]-5-nitrobenzonitrile (CAS no. 12236-25-8) is not auto-flammable.

Executive summary:

2-[[4-[bis(2-hydroxyethyl)amino]-o-tolyl]azo]-5-nitrobenzonitrile (CAS no. 12236-25-8) did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 2-[[4-[bis(2-hydroxyethyl)amino]-o-tolyl]azo]-5-nitrobenzonitrile (CAS no. 12236-25-8) is not auto-flammable.
