Results
The thermograms of the DSC runs PN9487 and PN9488 show in the temperature range of 110 °C – 190 °C an exothermic effect was observed, with an average energy of -100 J/g, directly followed by an endothermic effect in the temperature range of 190 – 270 °C (boiling).

Due to the exothermic decomposition before the endothermic effect the test item has no boiling point up to the decomposition temperature of 110 °C.
Final Results
The test item has no boiling point up to the decomposition temperature of 110 °C at atmospheric pressure (993 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995).
Thermal Stability
The DSC run PN9525 was performed in a closed glass crucible under an inert atmosphere. The DSC scan showed no thermal effects for the test item up to the final temperature of 300 °C.

Description of key information
The test item has no boiling point up to a decomposition temperature of 110 °C and 993 hPa (EU Method A.2, differential scanning calorimetry).
Key value for chemical safety assessment
Additional information
The test substance decomposes before boiling as determined according to E.U. Method A.2. In a supporting study the test substance showed no thermal effects up to the final temperature of 300 °C as determined according to OECD 113.
