other: It is how easily substance can burn or ignite, causing fire or combustion by brief contact with an ignition source.
Principles of method if other than guideline:
It is how easily substance can burn or ignite, causing fire or combustion by brief contact with an ignition source
GLP compliance:
not specified
Specific details on test material used for the study:
SMILES:CN(C)c1ccc(C(=C2C=CC(=N{+}(C)C)C=C2)c2c3ccc(S(=O)(=O)O{-}.[Na]{+})cc3cc(S(=O)(=O)O{-})c2O)cc1
Test procedure:
other: Not specified
Remarks on result:
other: Teat chemical 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:
hydrogen [4-[4-(dimethylamino)-α-(2-hydroxy-3,6-disulphonato-1-naphthyl)benzylidene]cyclohexa-2,5-dien-1-ylidene]dimethylammonium, monosodium salt 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 hydrogen [4-[4-(dimethylamino)-α-(2-hydroxy-3,6-disulphonato-1-naphthyl)benzylidene]cyclohexa-2,5-dien-1-ylidene]dimethylammonium, monosodium salt is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus hydrogen [4-[4-(dimethylamino)-α-(2-hydroxy-3,6-disulphonato-1-naphthyl)benzylidene]cyclohexa-2,5-dien-1-ylidene]dimethylammonium, monosodium salt was considered non-flammable for chemical safety assessment.
Executive summary:
