Description of key information

Appearance:

Based on available data from authoritative database, the chemical 1-(3-aminophenyl)urea was observed to be an organic solid in appearance.

Melting point:

Based on available data from authoritative database, the melting point of chemical 1-(3-aminophenyl)urea was determined to be 130 degree C.

Boiling point:

Based on available data from reliable sources such as authoritative database and safety data sheet,the boiling point of chemical 1-(3-aminophenyl)urea was determined to be 321.033 °C at 760 mm Hg.

Density:

Based on prediction done using ACD/I-Lab 2.0,the density of chemical 1-(3-aminophenyl)urea was estimated to be 1.350 ± 0.06 g/cm3.

Particle Size distribution:

The particle size distribution of 1-(3-aminophenyl)urea 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:

Modified Grain method (Mean of Antoine and Modified Grain methods) was used to estimate the vapour pressure of the substance1-(3-aminophenyl)ureausing MPBPVP v1.43 of EPI SUITE.

The estimated vapour pressure of the chemical at 25deg C was0.00351 Pa

Partition coefficient:

KOWWIN V1.68 was used to estimate the octanol water partition coefficient of the substance1-(3-aminophenyl)urea

The estimated logPOW of the chemical 1-(3-aminophenyl)urea was -0.7605

Water solubility:

WSKOW v1.42 was used to estimate the water solubility of the substance1-(3-aminophenyl)urea

The estimated water solubility of the chemical1-(3-aminophenyl)ureaat 25 deg C was 16380 mg/l

Based on the estimated value, the chemical1-(3-aminophenyl)ureawas soluble in water.

Surface tension:

Based on the data from ACD labs, surface tension of chemical 1-(3-aminophenyl)urea was predicted to be 71.9 ± 3.0 N/m.

Flash point:

Based on the Calculation done using  scientifically verified and validated formulas / equations ,the flash point of chemical 1-(3-aminophenyl)urea was estimated to be 156.99 degree C

Flammability:

1-(3-aminophenyl)urea 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 1-(3-aminophenyl)urea is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 1-(3-aminophenyl)urea 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 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
