Specific details on test material used for the study:
- Name of test material: Reaction mass of Methanaminium, N-​[4-​[[4-​(dimethylamino)​phenyl]​phenylmethylene]​-​2,​5-​cyclohexadien-​1-​ylidene]​-​N-​methyl-​ & acetate- Molecular formula: C25H28N2O2- Molecular weight: 388.508 g/mole- Smiles : [N+](=C1/C=CC(\C=C1)=C(\c1ccccc1)c1ccc(cc1)N(C)C)(\C)C.C(C)(=O)[O-]- Inchl: 1S/C23H25N2.C2H4O2/c1-24(2)21-14-10-19(11-15-21)23(18-8-6-5-7-9-18)20-12-16-22(17-13-20)25(3)4;1-2(3)4/h5-17H,1-4H3;1H3,(H,3,4)/q+1;/p-1- Substance type: Organic- Physical state: maroon lustrous liquid
Key result
Remarks on result:
other: The given chemical (CAS No. 41272-40-6) 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:
Reaction mass of Methanaminium, N-​[4-​[[4-​(dimethylamino)​phenyl]​phenylmethylene]​-​2,​5-​cyclohexadien-​1-​ylidene]​-​N-​methyl-​ & acetate did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that [4-[α-[4-(dimethylamino)phenyl]benzylidene]cyclohexa-2,5-dien-1-ylidene]dimethylammonium acetate is not auto-flammable.
Executive summary:

Reaction mass of Methanaminium, N-​[4-​[[4-​(dimethylamino)​phenyl]​phenylmethylene]​-​2,​5-​cyclohexadien-​1-​ylidene]​-​N-​methyl-​ & acetatee did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that Reaction mass of Methanaminium, N-​[4-​[[4-​(dimethylamino)​phenyl]​phenylmethylene]​-​2,​5-​cyclohexadien-​1-​ylidene]​-​N-​methyl-​ & acetate is not auto-flammable.
