Conclusions:
The substance decomposed from approximately 195 °C (468 K), at 100.7 to 101.7 kPa, by a thermal analysis method and use of differential scanning calorimetry, designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. As the test item decomposed, no value for boiling point of the parent test item could be determined.
Executive summary:

The substance decomposed from approximately 195 °C (468 K), at 100.7 to 101.7 kPa, by a thermal analysis method and use of differential scanning calorimetry, designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. As the test item decomposed, no value for boiling point of the parent test item could be determined.
