Melting point:
The melting point determination of 2-chloro-4-nitrophenol (CAS No. 619-08-9) was done following OECD Guideline 102 and according to the metal block capillary method. The test was conducted in replicates and mean melting temperature range was determine to be 107.3 - 111°C at 969.2 hPa.
Boiling Point:
The boiling point determination of 2-chloro-4-nitrophenol (CAS No. 619-08-9) was done following OECD Guideline 103 and according to the method of Siwoloboff. The test was conducted in replicates and mean boiling point was determine to be 190.3°C at 968.2 hPa.
Density:
The density of test item 2-chloro-4-nitrophenol (CAS No. 619-08-9)was determined following OECD Guideline 109 and according to the Adapted from ASTM D854-02 using glass pyknometerThe mean density of test item was determine to be 1.5421 g/cm³ at 20 °C and 968.7 hPa..
Particle size distribution:
The particle size distribution of test item 2-chloro-4-nitrophenol (CAS No. 619-08-9 ) was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determine to be in the range of 150 micron to 75 micron.
Vapour pressure:
Vapour pressure of 2-Chloro-4-nitrophenol estimated to be 0.1333 Pa at temperature 25 Deg C.
Partition coefficient:
Based on the available data from handbook, authoritative and modeling databases, the octanol water partition coefficient (log Pow) value of the test substance 2-Chloro-4-nitrophenol was estimated to be 2.55.
Water solubility:
Water solubility of 2-Chloro-4-nitrophenol is determine to be 1490 mg/L at temperature 25 Deg C.
Surface tension:
Based on the data from ACD labs, surface tension for 2-Chloro-4-nitrophenol was predicted to be 0.0622 N/m.
Flash point:
The flash point determination of Test item 2-chloro-4-nitrophenol (CAS No. 619-08-9 )was done. The method is closed cup method using Pensky-Martens Flash Point Apparatus. The mean flash point of the test item was determine to be 128°C at 968.2 hPa.
Auto flammability:
2-Chloro-4-nitrophenol did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 2-Chloro-4-nitrophenol is not auto-flammable.
Flammability:
2-Chloro-4-nitrophenol 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-Chloro-4-nitrophenol is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 2-Chloro-4-nitrophenol was considered non-flammable for chemical safety assessment.
Explosiveness:
The study does not need to be conducted because the substance contains chemical groups associated with explosive properties which include oxygen, but the calculated oxygen balance is less than - 200.
Oxidizing properties:
The study does not need to be conducted because the organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen and hence, the classification procedure does not need to be applied.
