Description of key information
Appearance / physical state / colour:
Based on available data from obtained report, the appearance of test chemical was observed to be a colorless liquid organic compound.
Melting point/ Freezing point:
The mean Freezing point of test chemical was observed with cooling curve method and it was observed to be -4.51 °C at 976.8 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 boiling point of test chemical is 266.5 °C at 979 .5 hPa
Density:
Based on available data from handbook and authoritative databases, the density of test chemical was determined in the range of 0.975 – 0.981 g/cm³
Particle size distribution (Granulometry):
The study does not need to be conducted because the substance is marketed or used in a non-solid or granular form.
Vapour pressure:
Modified Grain method (Mean of Antoine and Modified Grain methods) was used to estimate the vapour pressure of the test substance using MPBPVP v1.43 of EPI SUITE. The estimated vapour pressure of the test substance at 25 ° C was 0.907 Pa.
Partition coefficient:
The octanol water partition coefficient of test chemical was determined according to OECD guideline no 117 using reverse phase HPLC method. In this method reference substances used were namely Butanone, Benzene, Biphenyl, Toluene, Ethylbenzene, n-Butylbenzene, Naphthalene, Allyl phenyl ether having log Pow between range 0.3 -4.6 and calibration graph was prepared. And by using this graph, the octanol water partition coefficient of test chemical was determined to be 4.08.
Water solubility:
The water solubility observation of test chemical was done as per the OECD guideline 105 by spectrophotometric analytical method also as per OECD 101. The solubility of test chemical in water was observed to be 63.049 mg/L at 25°C.
Surface tension:
Based on the prediction, the surface tension for test chemical was predicted to be 34.3±3.0 dyne/cm.
Flash point:
The flash point observation of test substance was done as per the test guideline OECD 103. Closed cup method using Pensky-Martens Flash Point Apparatus were used. The flashpoint of the test substance was observed to be 99°C at 977.3 hPa. Thus according to observe value the given chemical was observed to be non-flammable.
Autoflammability:
Test chemical did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that test chemical is not auto-flammable.
Flammability:
The 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 the test chemical 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 there are no chemical groups present in the molecule which are associated with oxidizing properties and hence the classification procedure does not need to be applied.
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 1% w/v solution was determine to be 3.78 at 26 °C.
