Partition coefficient:
Water solubility:
The estimated water solubility of Benzenamine, 4-[(4-aminophenyl)(4-imino-2,5-cyclohexadien-1-ylidene)methyl]-, N-Me derivatives, molybdatesilicates at 25 deg C was 68100 mg/l.
Surface tension:
In accordance with column 2 of Annex VII of the REACH regulation, the study need only be conducted if surface activity is a desired property of the chemical. 1-dodecylpyridinium chloride (104-74-5) is used as a pigment used in paints applications. For this use, surface activity is not an important property. Hence this study was considered for waiver.
Flash point:
The flash point determination of Benzenamine, 4-[(4-aminophenyl)(4-imino-2,5-cyclohexadien-1-ylidene)methyl]-, N-Me derivatives, molybdatesilicates (CAS No. 68647-35-8)was done following closed cup method using Pensky-Martens flash point apparatus. The test was conducted in replicates and mean flash point was determine to be 216.6°C at 969.7hPa.
Auto flammability:
Benzenamine, 4-[(4 -aminophenyl)(4 -imino-2,5 -cyclohexadien-1 -ylidene)methyl]-, N-Me derivatives, molybdatesilicates did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that Benzenamine, 4 -[(4 -aminophenyl)(4 -imino-2,5 -cyclohexadien-1 -ylidene)methyl]-, N-Me derivatives, molybdatesilicates is not auto-flammable.
Flammability:
Benzenamine, 4-[(4 -aminophenyl)(4 -imino-2,5 -cyclohexadien-1 -ylidene)methyl]-, N-Me derivatives, molybdatesilicates 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 Benzenamine, 4 -[(4 -aminophenyl)(4 -imino-2,5 -cyclohexadien-1 -ylidene)methyl]-, N-Me derivatives, molybdatesilicates is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Benzenamine, 4 -[(4 -aminophenyl)(4 -imino-2,5 -cyclohexadien-1 -ylidene)methyl]-, N-Me derivatives, molybdatesilicates was considered non-flammable for chemical safety assessment.
Explosiveness:
The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties.
Oxidizing properties:
The study does not need to be conducted because the substance is a solid.
