Conclusions:
The boiling temperature of the test item has been determined to be: 259 ± 0.5 °C (532 ± 0.5 K) at 101.6 kPa atmospheric pressure.
Executive summary:

The boiling temperature was determined using EU Method A.2 and OECD TG 103 in the Differential Scanning Calorimetry (DSC) method under GLP. The test item was tested in triplicate. The mean boiling temperature was determined to be 258.55 °C (or 532 K) at 101.6 kPa atmospheric pressure in duplicate. There was no evidence of substance decomposition during the course of the test. The boiling point is considered to be 258.55 ± 0.5 °C (532 ± 0.5 K) at 101.6 kPa atmospheric pressure.
