The boiling point of chemical was estimated to be618.41˚C

Density:

Based on prediction done using ACD/I-Lab 2.0,the density of  chemical 7-(benzoylamino)-4-hydroxynaphthalene-2-sulfonic acid was estimated to be 1.535 ± 0.06 g/cm3

Particle size distribution:

The particle size distribution of 7-(benzoylamino)-4-hydroxynaphthalene-2-sulfonic acid 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 chemical7-(benzoylamino)-4-hydroxynaphthalene-2-sulfonic acidusing MPBPVP v1.43 of EPI SUITE.

The estimated vapour pressure of the chemical7-(benzoylamino)-4-hydroxynaphthalene-2-sulfonic acidat 25deg C was5.13E-012 Pa

Partition coefficient:

Based on available data from review article,the partition coefficient (log Pow) of chemical 7-(benzoylamino)-4-hydroxynaphthalene-2-sulfonic acid was determined to be 2.91

Water solubility:

WSKOW v1.42 was used to estimate the water solubility of the chemical7-(benzoylamino)-4-hydroxynaphthalene-2-sulfonic acid

The estimated water solubility of the chemical7-(benzoylamino)-4-hydroxynaphthalene-2-sulfonic acidat 25 deg C was 149330 mg/l

Based on the estimated value, the chemical7-(benzoylamino)-4-hydroxynaphthalene-2-sulfonic acidwas soluble in water.

Surface tension:

Based on the data from ACD labs, surface tension of chemical 7-(benzoylamino)-4-hydroxynaphthalene-2-sulfonic acid was predicted to be 78.6 ± 3.0 N/m

Flash point:

Based on the Calculation done using  scientifically verified and validated formulas / equations ,the flash point of chemical 7-(benzoylamino)-4-hydroxynaphthalene-2-sulfonic acid was estimated to be 393.054 degree C.

Auto flammability:

7-(benzoylamino)-4-hydroxynaphthalene-2-sulfonic acid did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 7-(benzoylamino)-4-hydroxynaphthalene-2-sulfonic acid is not auto-flammable.

Flammability:

7-(benzoylamino)-4-hydroxynaphthalene-2-sulfonic acid 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 7-(benzoylamino)-4-hydroxynaphthalene-2-sulfonic acid is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 7-(benzoylamino)-4-hydroxynaphthalene-2-sulfonic acid 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
