Density:

Based on prediction done using ACD/I-Lab 2.0,the density of Aluminium, 3-hydroxy-4 -[(4 -sulfo-1 -naphthalenyl)azo]-2,7 -naphthalenedisulfonic acid complex was estimated to be 1.82 g/cm3.

Particle size distribution:

The particle size distribution of Aluminium, 3-hydroxy-4-[(4-sulfo-1-naphthalenyl)azo]-2,7-naphthalenedisulfonic acid complex 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 the test substance Aluminium, 3-hydroxy-4-[(4-sulfo-1-naphthalenyl)azo]-2,7-naphthalenedisulfonic acid complex (CAS no. 12227-62-2) at 25deg C was 6.02E-21 Pa (4.51E-23 mm Hg).

Partition coefficient:

Based on the available data from modeling database using the KOWWIN V1.68 program, the estimated partition coefficient (log Pow) value of the substance Aluminium, 3 -hydroxy-4 -[(4 -sulfo-1 -naphthalenyl)azo]-2,7 -naphthalene disulfonic acid complex was 1.63.

Water solubility:

The estimated water solubility of Aluminium, 3-hydroxy-4-[(4-sulfo-1-naphthalenyl)azo]-2,7-naphthalenedisulfonic acid complex at 25 deg C was 0.0017 mg/l.

Surface tension:

Based on the data from ACD labs, surface tension for Aluminium, 3-hydroxy-4-[(4-sulfo-1-naphthalenyl)azo]-2,7-naphthalenedisulfonic acid complex was predicted to be 0.0873 N/m.

Flash point:

Flash point of Aluminium, 3-hydroxy-4-[(4-sulfo-1-naphthalenyl)azo]-2,7-naphthalenedisulfonic acid complex is calculated at 1 atm. Pressure to be 633.38 Deg C.

Auto flammability:

Aluminium, 3-hydroxy-4-[(4-sulfo-1-naphthalenyl)azo]-2,7-naphthalenedisulfonic acid complex did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that Aluminium, 3-hydroxy-4 -[(4 -sulfo-1 -naphthalenyl)azo]-2,7 -naphthalenedisulfonic acid complex is not auto-flammable.

Flammability:

Aluminium, 3-hydroxy-4 -[(4 -sulfo-1 -naphthalenyl)azo]-2,7 -naphthalenedisulfonic acid complex 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 Aluminium, 3 -hydroxy-4 -[(4 -sulfo-1 -naphthalenyl)azo]-2,7 -naphthalenedisulfonic acid complex is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Aluminium, 3 -hydroxy-4 -[(4 -sulfo-1 -naphthalenyl)azo]-2,7 -naphthalenedisulfonic acid complex 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.
