Description of key information
Additional information
Appearance/physical state/colour
On the basis of physical observation and using the sense of smell (3-aminophenyl) uronium chloride was found to be an amorphous off-white odourless organic chemical substance.
Melting point/freezing point
The melting point of the chemical (3-aminophenyl) uronium chloride by the capillary method was determined to be 115oC at 990 hPa. There was no decomposition or sublimation of the substance. This value at 101 325 Pa is equivalent to 117.700oC.
Boiling point
The Substance (3-aminophenyl) uronium chloride was found to have a boiling point of 330oC at atmospheric pressure of 990 hPa. This value at 101 325a is equivalent to 337.75oC
Density
The bulk density of (3-aminophenyl) uronium chloride by the mass by volume method was found to be 0.634 g/cm3 at room temperature of 33 deg C. The relative density at 20oC is equivalent to 1.04 g/cm3
Particle size distribution (Granulometry)
The particle size distribution (granulometry) of (3-aminophenyl) uronium chloride by the sieve analysis method was found to be in the range of 53 micrometer to 500 micrometer. Majority of the particles were found to be in the size 500 (45.66%) - 330 (27.17%) micrometer in size.
Vapour pressure
Vapour pressure of (3-aminophenyl)uronium chloride is estimated to be 0.0000263 mmHg (Modified Grain Method). This value is equivalent to 0.00350 Pa
Partition coefficient
The experimental value of octanol water partition co-efficient (log Pow) of of (3-aminophenyl) uronium chloride by Shake flask method was found to be -0.9136 at temperature 33 deg C and pH of 3.70.This value indicates that (3-aminophenyl)uronium chloride is hydrophilic in nature.
Water solubility
The experimental value of the water solubility of (3-aminophenyl)uronium chloride was found to be 3700 mg/L at temperature of 33deg C indicating that (3-aminophenyl)uronium chloride is soluble in water.
Solubility in organic solvents / fat solubility
The experimental value of solubility of (3-aminophenyl)uronium chloride in methanol at temperature of 33deg C was found to be 2100 mg/L indicating that (3-aminophenyl) uronium chloride is soluble in methanol. This value at 20oC is equivalent to 1272.72 mg/L.
Surface tension
In accordance with column 2 of Annex VII of the REACH regulation, this end point was considered for waiver since since surface activity is not a desired property of the chemical
Flash point
Flash point of (3-aminophenyl)uronium chloride was estimated to be 148 °C as per the ChemSpider Database which is considered to be a reliable data source
Auto flammability
(3-aminophenyl)uronium chloride did not catch fire on being exposed to air at room temperature of 33 deg C and atmospheric pressure of 990 hPa. This indicates (3-aminophenyl)uronium chloride is not auto-flammable.
Flammability
From the experimental values of flammability, (3-aminophenyl) uronium chloride ignited when the flame of Bunsen burner having temperature of 950 deg C was brought in contact with it. Thus it can be concluded that (3-aminophenyl)uronium chloride is flammable only at high temperature of about 950 deg C. However since such high temperatures are not found under normal circumstances of transportation and use, (3-aminophenyl) uronium chloride was considered non-flammable for chemical safety assessment.
Explosiveness
According to theoretical considerations based on chemical structure, (3-aminophenyl) uronium chloride does not possess explosive properties. The reason for this is there are no chemical groups associated with explosive properties in (3-aminophenyl) uronium chloride. Thus, as per column 2 of Annex VII this end point was considered for waiver.
Oxidising properties
(3-aminophenyl) uronium chloride was found to have mild oxidation potential since 270.81 ml of KMnO4 was required for getting the end point of the redox titration for 100 g of (3-aminophenyl) uronium chloride. However, this oxidation potential was considered high enough for classifying the chemical as an oxidising solid
Stability in organic solvents and identity of relevant degradation products
(3-aminophenyl) uronium chloride was found to be stable in organic solvent dichloro methane and no degradation products were formed after 24 hours as evident from the GC-MS chromatogram obtained at 0 hours and that obtained after 24 hours.
Viscosity
This end point was considered for waiver since viscosity is an inherent property of a liquid that offers resistance to its flow and (3-aminophenyl) uronium chloride is a solid substance and hence this testing was considered scientifically unjustified for (3-aminophenyl) uronium chloride.
