Flammability:
9,10-Anthracenedione, 1,4-diamino-, N,N'-bis(4-C7-17-branched alkylphenyl) derivs. 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 9,10-Anthracenedione, 1,4-diamino-, N,N'-bis(4-C7-17-branched alkylphenyl) derivs. is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 9,10-Anthracenedione, 1,4-diamino-, N,N'-bis(4-C7-17-branched alkylphenyl) derivs. was considered non-flammable for chemical safety assessment.

The pH determination of test item 9,10-Anthracenedione, 1,4-diamino-, N,N'-bis(4-C7-17-branched alkylphenyl) derivs. (CAS No 97862-23-2) was done following OECD guideline 122. pH of 1% w/v emulsion was measured with the help of pH meter and it was observed to be 5.87at 29 °C.
Dissociation constant:
The study does not need to be conducted because the substance is insoluble.
Viscosity:
The viscosity determination of Test item 9,10-Anthracenedione, 1,4-diamino-, N,N'-bis(4-C7-17-branched alkylphenyl) derivs. (CAS No. 97862-23-2 )was done as per the test guideline OECD 114 using Redwood Viscometer No. 1.
