Endpoint summary
Administrative data
Description of key information
Appearance:
On the basis of physical observation and using the sense of smell, 2-aminonaphthalene-1,5-disulfonic acid was observed to be a solid.
Melting point:
Based on available data from reliable handbook, the chemical 2-aminonaphthalene-1,5-disulfonic acid was determined to be >300 degree C.
Boiling point:
The study does not need to be conducted because the substance is a solid which melts above 300°C
Density:
Based on prediction done using ACD/I-Lab 2.0,the density of chemical 2-aminonaphthalene-1,5-disulfonic acid was estimated to be 1.769±0.06 g/cm3.
Particle Size Distribution:
The particle size distribution of test item 2-aminonaphthalene-1,5-disulfonic acid was determined by granulometric analysis with rotap sieve shaker.The particle size distribution was determined to be in the range of 150- 25 microns.
Vapor Pressure:
The study does not need to be conducted since the melting point is above 300 deg C
The melting point of 2-aminonaphthalene-1,5-disulfonic acid was determined to be >300 degree C. Hence, this endpoint was considered for waiver
Surface tension:
Based on the data from ACD labs, surface tension for 2-aminonaphthalene-1,5-disulfonic acid was predicted to be 90.1 ± 3.0 dyne/cm.
Flash point:
The flash point determination of2-aminonaphthalene-1,5-disulfonic acid(CAS No. 117 -62 -4) was done as per the test guideline OECD 103. The method is closed cup method using Pensky Martin’s Flash Point Apparatus. The flashpoint of the test substance was determined to be 95°C at 980.9 hPa.Based on criteria mentioned in CLP regulation the chemical has flash point >than 60 degree C hence the substance was considered to be non-flammable.
Autoflammability:
2-aminonaphthalene-1,5-disulfonic acid did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 2-aminonaphthalene-1,5-disulfonic acid is not auto-flammable.
Flammability:
2-aminonaphthalene-1,5-disulfonic 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 2-aminonaphthalene-1,5-disulfonic acid is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 2-aminonaphthalene-1,5-disulfonic acid was considered non-flammable for chemical safety assessment.
Partition Coefficient:
Data from authoritative databases suggests that the estimated octanol water partition coefficient [log Pow] of 2-aminonaphthalene-1,5-disulfonic acid was -1.85.
Based on this value, it can be concluded that 2-aminonaphthalene-1,5-disulfonic acid is hydrophillic in nature.
Water Solubility:
The estimated solubility of 2-aminonaphthalene-1,5-disulfonic acid in water at 25 deg C lies in the range of 4490 - 4494 mg/l.
This value suggests that 2-aminonaphthalene-1,5-disulfonic acid is soluble in water.
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 oxidising properties and hence, the classification procedure does not need to be applied
Viscosity:
The study does not need to be conducted because the substance is a solid
