Specific details on test material used for the study:

- Name of test material (as cited in study report): 2-Naphthalenol, 1-[[2-methyl-4-[(2-methylphenyl) azo] phenyl] azo]-, ar-styrenated- IUPAC name: 2-Naphthalenol, 1-[[2-methyl-4-[(2-methylphenyl) azo] phenyl] azo]-, ar-styrenated- Molecular formula: C40H36N4O1 - Molecular wt. : 588.76 g/mole- smiles : Cc1ccccc1N=Nc2ccc(c(C)c2)N=Nc3c4ccc(C(C)c5ccccc5)cc4cc(C(C)c6ccccc6)c3O- Substance type: Organic- Physical state: red liquid

Key result

Remarks on result:

other: Chemical (CAS no. 85203-90-3) 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-Naphthalenol, 1-[[2-methyl-4-[(2-methylphenyl)azo]phenyl]azo]-, ar-styrenated did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 2-Naphthalenol, 1-[[2-methyl-4-[(2-methylphenyl)azo]phenyl]azo]-, ar-styrenated is not auto-flammable.

Executive summary:

2-Naphthalenol, 1-[[2-methyl-4-[(2-methylphenyl)azo]phenyl]azo]-, ar-styrenated did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that   2-Naphthalenol, 1-[[2-methyl-4-[(2-methylphenyl)azo]phenyl]azo]-, ar-styrenated is not auto-flammable.
