Key result
Remarks on result:
other: Chemical (CAS no. 15876-47-8) 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:
Aluminium(3 +) ion (5E)-6 -oxo-5 -[2 -(4 -sulfonatonaphthalen-1 -yl)hydrazin-1 -ylidene]-5,6 -dihydronaphthalene-1,3 -disulfonate did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that  aluminium(3 +) ion (5E)-6 -oxo-5 -[2 -(4 -sulfonatonaphthalen-1 -yl)hydrazin-1 -ylidene]-5,6 -dihydronaphthalene-1,3 -disulfonate is not auto-flammable.
Executive summary:

Aluminium(3 +) ion (5E)-6 -oxo-5 -[2 -(4 -sulfonatonaphthalen-1 -yl)hydrazin-1 -ylidene]-5,6 -dihydronaphthalene-1,3 -disulfonate did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that  aluminium(3 +) ion (5E)-6 -oxo-5 -[2 -(4 -sulfonatonaphthalen-1 -yl)hydrazin-1 -ylidene]-5,6 -dihydronaphthalene-1,3 -disulfonate is not auto-flammable.
