Additional information

A measured boiling point value of 198.4°C (471.6 K) at 1013 hPa was determined for the substance using a photocell detection (capillary) method in accordance with OECD Test Guideline 103 and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable and is selected as key study. In addition to the photocell detection method, a DSC method was also performed by the same author (Haas 2017). In the DSC method, boiling point value of 198.8°C at 963 hPa was obtained for the submission substance.

Also, a predicted boiling point of 190°C at 1013 hPa was obtained for the substance using a validated QSAR estimation method.

In available secondary sources to which reliability could not be assigned, boiling point values of 194°C and 210°C at 1013 hPa were reported for the substance.
