Key result
Remarks on result:
other: The given chemical (CAS no. 6320-14-5) 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:
2-[3-(1,3-dihydro-1,3,3-trimethyl-2H-indol-2-ylidene)prop-1-enyl] -1,3,3-trimethyl-3H-indolium chloride (CAS no. 6320-14-5) did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 2-[3-(1,3-dihydro-1,3,3-trimethyl-2H-indol-2-ylidene)prop-1-enyl] -1,3,3-trimethyl-3H-indolium chloride (CAS no. 6320-14-5) is not auto-flammable.
Executive summary:

2-[3-(1,3-dihydro-1,3,3-trimethyl-2H-indol-2-ylidene)prop-1-enyl] -1,3,3-trimethyl-3H-indolium chloride (CAS no. 6320-14-5) did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 2-[3-(1,3-dihydro-1,3,3-trimethyl-2H-indol-2-ylidene)prop-1-enyl] -1,3,3-trimethyl-3H-indolium chloride (CAS no. 6320-14-5) is not auto-flammable.
