53585 -53 -8
State of the substance colorless to yellow liquid
Melting/Freezing point -38.5 - -32.8 °C (a melting range ist stated)
Boiling point decomposition at 265 °C; calculated boiling point: 273 °C (based on method of Banks); 389.6 °C (based on EPA method)
Relative density 1.0441 at 20 °C 
Vapour pressure 0.00101 Pa at 20 °C; 0.00162 Pa at 25°C
Surface tension waiving: Based on the structure of the submission substance surface activity is not expected. In addition, the solubility of the material is below 1 mg/L at 20 °C.
Water solubility 18 µg/L at 20 °C
Partition coefficient, logPow > 6 at 22 °C
Flash point 212 °C at 1013 hPa
Flammability Waiving: Based on the structural composition and based on experience during use as Heat Transfer Fluid it is well known that the material is not pyrophoric.
Explosive properties Waiving: The submission substance does not contain any chemical group that is associated with explosive properties. The substance is used as Heat Transfer Fluid at higher temperature and therefore absence of explosive properties is well known.
Ignition temperature 500 °C
Oxidizing Properties Waiving: The submission substance is incapable of reacting exothermically with combustible materials since the chemical structure does not contain oxygen.
Granulometry Waiving:  submission substance is a liquid at ambient temperature and marketed as such
Stability in organic solvents Waiving: Stability of the test substance is not considered to be critical
Viscosity (static) 47.94 mm²/s at 20 °C; 16.35 mm²/s at 40 °C

Dissociation constant 

 Waiving: The submission substance cannot dissociate due to a lack of relevant functional groups.
