Key result
Test procedure:
other: not specified
Remarks on result:
other: 2-[[(4-methoxyphenyl)methylhydrazono]methyl]-1,3,3-trimethyl-3H-indolium acetate 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:
2,2'-[(3,3'-dimethyl[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-nonylphenol] (CAS no. 67990-27-6) 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 2,2'-[(3,3'-dimethyl[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-nonylphenol] (CAS no. 67990-27-6) is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 2,2'-[(3,3'-dimethyl[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-nonylphenol] (CAS no. 67990-27-6) was considered non-flammable.
Executive summary:

2,2'-[(3,3'-dimethyl[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[4-nonylphenol] (CAS no. 67990-27-6) does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it.
