Thermal Stability
The test item showed three exothermic effects in the temperature ranges of 110 °C – 160 °C, 170 °C – 200 °C and 250 °C – 300 °C with an overall decomposition energy of -90 J/g.

Conclusions:
The substance is thermal stable at ambient conditions.
Executive summary:

A study was conducted according to OECD guideline 113 to determine the thermal stability of the test item using DSC measurement. One measurement with about 9 mg of the test item in a closed glass crucible under air was performed. The crucible was heated up from room temperature to 300 °C with a heating rate of 3 K/min. The test item showed three exothermic effects in the temperature ranges of 110 °C – 160 °C, 170 °C – 200 °C and 250 °C – 300 °C with an overall decomposition energy of -90 J/g. According to the OECD guideline 113 criteria the test item was considered to be thermal stable at room temperature as no significant decomposition or chemical transformation was found below 150 °C.
