Description of key information
Appearance / physical state / colour:
The appearance of 4-(phenylazo)benzene-1,3-diamine acetate was observed to be a solid organic compound.
Melting point/ Freezing point:
Based on prediction done using MPBPVP v1.43, the melting point of chemical 4-(phenylazo)benzene-1,3-diamine acetate was estimated to be 4 -(phenylazo)benzene-1,3-diamine acetate 55.8 °C.
Boiling point:
Based on prediction done using MPBPVP v1.43, the Boiling point of chemical 4-(phenylazo)benzene-1,3-diamine acetate was estimated to be 254 °C
Density:
The density of chemical 4-(phenylazo)benzene-1,3-diamine acetate was estimated to be 1.43 ± 0.1 g/cm3.
Particle size distribution (Granulometry):
The particle size distribution of 4-(phenylazo)benzene-1,3-diamine acetate was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determined to be in the range of 147 micron to 52 micron.
Vapour pressure:
The vapour pressure of the test substance 4-(phenylazo)benzene-1,3-diamine acetate is determined at 25 deg C was 0.000016 Pa (1.19E-07 mmHg).
Partition coefficient:
The octanol water partition coefficient of target chemical 4-(phenylazo)benzene-1,3-diamine acetate (CAS no. 79234-33-6) was determined to be 1.11 dimensionless . On the basis of log Pow value the test chemical 4-(phenylazo)benzene-1,3-diamine acetate was considered to be hydrophilic in nature which is also supported by the solubility of this chemical in water.
Water solubility:
The estimated water solubility of test substance 4-(phenylazo)benzene-1,3-diamine acetate at 25 deg C was 238000 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. The given chemical 4-(phenylazo)benzene-1,3-diamine acetate is used as a dye in paper industry, etc. For this use, surface activity is not an important property. Hence this study was considered for waiver.
Flash point:
The flash point of 4-(phenylazo)benzene-1,3-diamine acetate is determined to be 214.8 °C.
Autoflammability:
4-(phenylazo)benzene-1,3-diamine acetate did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 4-(phenylazo)benzene-1,3-diamine acetate is not auto-flammable.
Flammability:
4-(phenylazo)benzene-1,3-diamine acetate 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 4-(phenylazo)benzene-1,3-diamine acetate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 4-(phenylazo)benzene-1,3-diamine acetate 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.
Oxidising properties:
The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidizing properties and hence the classification procedure does not need to be applied.
