Boiling Point. The test item was determined to decompose from approximately 127 °C (400 K) at 100.7 to 101.6 kPa. Decomposition was observed both in air and under a nitrogen atmosphere. Therefore, due to thermal decomposition, the boiling point cannot be determined for this substance.Testing was performed by differential scanning calorimetry, using a procedure 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.

Discussion
From comparison of the thermogram profiles obtained from samples analysed using pre‑perforated crucible lids (which allow self-pressurisation up to the boiling temperature) and those using manually pierced crucible lids (i.e. an open system), it is possible to evaluate if an observed endotherm originates from a true boiling temperature for the test item.
For determinations 1 and 2, performed using the pre-perforated crucible lids, no significant endotherms were observed prior to obvious ongoing decomposition of the test item. For the determinations performed in a manually pierced crucible, determinations 3 to 5 inclusive, a minor, broad endotherm was observed from approximately 60 °C. However, as this thermal event was suppressed by the pre-perforated crucible lids, this endotherm can be confidently attributed to evaporation only, as opposed to a true boiling temperature for any individual component present in the test item. The influence of this endotherm on the overall thermogram profile was the reason that determinations 1 and 2 only were considered for quantification of the test item decomposition. Decomposition was further supported by the test item residues remaining on completion of all determinations.
Due to the low initial rate of enthalpy change during decomposition, the onset temperature could only be approximated. Due to the variance observed, a limit value has been reported based on the lowest observed onset temperature.
The use of manually pierced crucibles (an open system) also provided an opportunity to assess the stability of the test item in air and in an inert atmosphere (nitrogen). Decomposition was observedboth in air and under a nitrogen atmosphere, indicating the process was most likely thermal and not oxidative.
