Endpoint summary
Administrative data
Description of key information
Appearance:
Based on available data from reliable sources such as hanbook and authorative database ,the substance 4-Nitro-m-phenylenediamine was observed to be an organic Orange coloured solid prisms from water in appearance
Melting point:
Based on available data from reliable sources such as authoritative databases and handbook, the melting point value of chemical 4-Nitro-m-phenylenediamine substance was determined to be 161 deg C.
Boiling point:
Based on the prediction done using the EPI Suite MPVPBP V1.43,the Boiling point of chemical4-nitrobenzene-1,3-diaminewas predicted.
The boiling point of chemical4-nitrobenzene-1,3-diaminewas estimated to be 326.23 ˚C
Density:
Based on available data from authoritative database,the density of chemical 4-nitrobenzene-1,3-diamine was determined to be 1.552 g/cm3 at 19.85 degree C.
Particle Size Distribution:
The particle size distribution of test item 4-Nitro-m-phenylenediamine was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was found to be in the range of 150 micron to 25 micron.
Vapor Pressure:
Data from various authoritative databases suggests that the estimated vapor pressure of 4-nitro-m-phenylene diamine at 25 deg C was 0.00747 Pa.
Partition Coefficient:
Data from various authoritative databases suggests that the estimated octanol water partition coefficient (logPow) of 4-nitro-m-phenylenediamine was 0.55.This value indicates that 4-nitro-m-phenylene diamine is hydrophillic in nature.
Water Solubility:
A study was conducted to determine the water solubility of 4 -nitro-m-phenylene diamine. The water solubility of 4-nitro-m-phenylene diamine at 15 deg C was 1000 mg/l.
Data from various authoritative databases suggests that the estimated water solubility of 4-nitro-m-phenylene diamine at 25 deg C was 24850 mg/l.
The experimental and estimated values indicate that 4 -nitro-m-phenylene diamine is soluble in water.
Surface tension:
Based on the data from ACD labs, surface tension for4-nitrobenzene-1,3-diaminewas predicted to be 77.9 ± 3.0 dyne/cm.
Flash point:
The flash point of 4-nitrobenzene-1,3-diamine (5131-58-8) was calculated to be 160.79 degree C. Based on criteria mentioned in CLP regulation the substance 4-nitrobenzene-1,3-diamine (5131-58-8) was considered to be non flammable.
Autoflammability:
From the available data from Gestis database, the auto ignition temperature for 4-nitrobenzene-1,3-diamine was determined to be >500 degree C.
Flammability:
4-nitrobenzene-1,3-diamine 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 4-nitrobenzene-1,3-diamine is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 4-nitrobenzene-1,3-diamine was considered non-flammable for chemical safety assessment.
Explosiveness:
In accordance with column 2 of Annex VII of the REACH regulation, the study does not need to be conducted since there are no chemical groups associated with explosive properties except nitro group which does not contribute to the explosive property of a chemical 4-nitro-m-phenylenediamine. Thus, this end point was considered for waiver and the chemical is considered to be "Non explosive".
Oxidising properties:
In accordance with column 2 of Annex VII of the REACH regulation, the substance 4-nitro-m-phenylenediamine is incapable of reacting exothermically with combustible materials on the basis of the chemical structure. It is an organic substance containing oxygen but no halogen atom and these elements are not chemically bonded to nitrogen or oxygen. Thus, the chemical is likely to be "Non-oxidising".
Viscosity:
The study does not need to be conducted because the substance is a solid
