Description of key information
Appearance:
On the basis of physical observation and using the sense of smell, 3,7-bis(diethylamino)phenoxazin-5-ium acetate was observed to be a solid.
Melting point:
Based on prediction done using MPBPVP v1.43, the melting point of 3,7-bis(diethylamino)phenoxazin-5-ium acetate was estimated to be 308.95 C.
Boiling Point:
Based on prediction done using MPBPVP v1.43, the Boiling point of 3,7-bis(diethylamino)phenoxazin-5-ium acetate was estimated to be 706.27 ˚C.
Density:
The density of 3,7-bis(diethylamino)phenoxazin-5-ium acetate is 1.102 g/cm3 at 20°C and 981.6 hPa.
Particle size distribution:
The particle size distribution of 3,7-bis(diethylamino)phenoxazin-5-ium acetate was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determined to be in the range of 150 micron to 53 micron.
Vapour pressure:
The estimated vapour pressure of 3,7-bis(diethylamino)phenoxazin-5-ium acetate at 25 deg C was 2.69E-9 Pa.
Partition coefficient:
The estimated logPOW of the test substance 3,7-bis(diethylamino)phenoxazin-5-ium acetate was 4.4. Based on the estimated value, the test substance 3,7-bis(diethylamino)phenoxazin-5-ium acetate can be considered as hydrophobic in nature, which is also supported by the water solubility of the test substance 3,7-bis(diethylamino)phenoxazin-5-ium acetate.
Water solubility:
The estimated water solubility of 3,7-bis(diethylamino)phenoxazin-5-ium acetate at 25 deg C was 0.050999999 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. 3,7-bis(diethylamino)phenoxazin-5-ium acetate is used as a dye. For this use, surface activity is not an important property. Hence this study was considered for waiver.
Flash point:
The flash point of 3,7-bis(diethylamino)phenoxazin-5-ium acetate is greater than 300 °C at 980.9 hPa.
Auto flammability:
3,7-bis(diethylamino)phenoxazin-5-ium acetate did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 3,7-bis(diethylamino)phenoxazin-5-ium acetate is not auto-flammable.
Flammability:
3,7-bis(diethylamino)phenoxazin-5-ium 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 3,7-bis(diethylamino)phenoxazin-5-ium acetate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 3,7-bis(diethylamino)phenoxazin-5-ium 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.
Oxidizing properties:
The study does not need to be conducted because the organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen and hence, the classification procedure does not need to be applied.
Stability in organic solvents and identity of relevant degradation products :
The study does not need to be conducted because the stability of the substance is not considered to be critical.
Dissociation constant :
The study does not need to be conducted because the substance is readily oxidisable in water.
Viscosity :
The study does not need to be conducted because the substance is a solid.
