Key result
Remarks on result:
other: 2-[[4-[bis(2-hydroxyethyl)amino]-o-tolyl]azo]-5-nitrobenzonitrile not ignited when the flame of bunsen burner having temperature of approximately 950°C was brought in contact with it.
Interpretation of results:
other: non flammable
Conclusions:
2-[[4-[bis(2-hydroxyethyl)amino]-o-tolyl]azo]-5-nitrobenzonitrile (CAS no. 12236-25-8) does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that 2-[[4-[bis(2-hydroxyethyl)amino]-o-tolyl]azo]-5-nitrobenzonitrile (CAS no. 12236-25-8) is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 2-[[4-[bis(2-hydroxyethyl)amino]-o-tolyl]azo]-5-nitrobenzonitrile (CAS no. 12236-25-8) was considered non-flammable for chemical safety assessment.
Executive summary:

2-[[4-[bis(2-hydroxyethyl)amino]-o-tolyl]azo]-5-nitrobenzonitrile (CAS no. 12236-25-8) does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it.
