Density:
The density of chemical 3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl chloride was estimated to be 1.472 ± 0.06 g/cm3, at 20 °C and 760 mmHg pressure.
Particle size distribution (Granulometry):
The particle size distribution of 3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl chloride was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determined to be in the range of 149 micron to 53 micron.
Vapour pressure:
The estimated vapour pressure of the substance 3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl chloride at 25 deg C was 0.0004 Pa.
Partition coefficient:
Octanol water partition coefficient of the 3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl chloride (CAS no. 4462-55-9) was estimated. The estimated log POW of the 3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl chloride was 3.26. On the basis of estimated value, the 3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl chloride can be considered as hydrophillic in nature.
Water solubility:
The estimated water solubility of substance 3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl chloride at 25 deg C was 22.98 mg/l
Surface tension:
The surface tension for chemical 3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl chloride was predicted to be 48.9 ± 3.0 dyne/cm.
Flash point:
The flash point of 3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl chloride was estimated as 190.2 ± 27.9 °C.
Autoflammability:
3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl chloride did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl chloride is not auto-flammable.
Flammability:
3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl chloride 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 3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl chloride is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 3-(2,6-dichlorophenyl)-5-methyl-1,2-oxazole-4-carbonyl chloride 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.
