not specified
Test material information:
Composition 1
Specific details on test material used for the study:
- Name of test material: 1-[(2-methoxyphenyl)azo]-2-naphthol
- Molecular formula: C17 H14 N2 O2
- Molecular weight: 278.31 g/mol
- Smiles notation: c12c(\N=N\c3c(cccc3)OC)c(ccc1cccc2)O
- InChl : 1S/C17H14N2O2/c1-21-16-9-5-4-8-14(16)18-19-17-13-7-3-2-6-12(13)10-11-15(17)20/h2-11,20H,1H3/b19-18+
- Substance type: Organic
- Physical state: solid
Test procedure:
other: not specified
Remarks on result:
other: 1-[(2-methoxyphenyl)azo]-2-naphthol 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:
1-[(2-methoxyphenyl)azo]-2-naphthol 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 1-[(2-methoxyphenyl)azo]-2-naphthol is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 1-[(2-methoxyphenyl)azo]-2-naphthol was considered non-flammable for chemical safety assessment.
Executive summary:

1-[(2-methoxyphenyl)azo]-2-naphthol 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 1-[(2-methoxyphenyl)azo]-2-naphthol is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 1-[(2-methoxyphenyl)azo]-2-naphthol was considered non-flammable for chemical safety assessment.
