Description of key information
Appearance:
On the basis of physical observation and using the sense of smell, test chemicalwas observed to be a dark blue solid powder.
Melting point:
The melting point determination of Test chemical was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The Mean Melting temperature range was determine to be 191.3 -195.8 °C at 981.5 hPa.
Boiling Point:
The boiling point determination of Test chemical was done as per the test guideline OECD 103. The method followed was according to Siwoloboff. The mean boiling point was determine to be greater than 300°C at 980.9 hPa.
Density:
The density of Test chemical was determined following OECD guideline 109 and according to the method adapted from ASTM D 854-02. The mean density of the test chemical was determine to be 1.4910 g/cm³ at 20°C and 979.6 hPa.
Particle size distribution:
The particle size distribution of test chemical was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determine to be in the range of 150 micron to 25 micron.
Vapour pressure:
The estimated vapour pressure of test substance at 25 Deg C was 1.50E-37 hPa.
Partition coefficient:
The partition coefficient (n-octanol/water) of test substance was determined as per the HPLC method (OECD Guideline-117).
The Log Pow value was determine to be 4.181 ± 0.002 at 25°C.
Water solubility:
The water solubility determination of test chemical was done as per the OECD guideline 105 by spectrophotometric analytical method as per OECD 101. The solubility of test chemical in water was determine to be less than 0.01 mg/L at temperature 25°C.
From this value it is concluded that test chemical is insoluble in water.
Surface tension:
The study does not need to be conducted because based on structure, surface activity is not expected or cannot be predicted.
Flash point:
The study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids.
Auto flammability:
Auto flammability of test chemical is determine to be greater than 350 Deg C.
From this value it is concluded that test chemical is auto flammable only at higher temperatures.
Flammability:
Test chemical 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 Test chemical is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Test chemical was considered non-flammable
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.
Oxidizing properties:
The study does not need to be conducted because the substance is a solid.
pH:
The pH determination of test chemical was done as per the test guideline OECD 122. The mean pH of the test dispersion was determined with the help of digital pH meter. The mean pH was determined to be 5.70 at 25.0 °C.

Vapour pressure:
Modified Grain method was used to estimate the vapour pressure of test substance using MPBPVP v1.43 of EPI SUITE.
The estimated vapour pressure of test substance at 25 Deg C was 1.50E-37 hPa.
Partition coefficient:
The partition Coefficient n-octanol/water of test chemical was determined by the Reverse Phase High Performance Liquid Chromatographic method according to OECD Guideline No.117 for testing of Chemicals. The reference substances were chosen according to estimated Pow range of the test substance and generalized calibration graph was prepared. The reference substances were Butanone, Acetophenone, Benzophenone, 4-Methoxyphenol, Phenol, Benzene, Biphenyl, Methyl benzoate, Benzyl Benzoate, 1,4-Dichlorobenzene, 1,2,4-Trichlorobenzene, Chlorobenzene, 2,6-Diphenylpyridine, Bromobenzene, 2,3-Dichloroaniline, Triphenylamine, 4-Acetylpyridine, Acetanilide, 2,4-Dinitrophenol, 2-Nitrophenol, Nitrobenzene, 2,6-Dichlorobenzonitrile, Diphenylamine, Cinnamyl alcohol, 4 -Methylbenzyl alcohol, Benzyl alcohol, Phenoxyacetic acid, Cinnamic Acid, 3-Nitrobenzoic acid, 3-Methylbenzoic acid, 3-Chlorobenzoic acid, Toluene, Ethylbenzene, n-Butylbenzene, Naphthalene, Diphenyl ether, Allyl phenyl ether, DDT having Pow value ranging from 0.3 to 6.2.
