Additional information

Two boiling point studies were performed for the submission substance. In the study conducted using a Differential Scanning Calorimetry (DSC) method, no clear boiling point (very broad endothermic peak) was detected for the substance. In the second study using a photocell detection method in accordance with EU Method A.2 and in compliance with a known quality system (ISO 9001:2008), a boiling point of 315°C (588.2 K) at 1013 hPa was determined for the submission substance. This result is considered to be reliable and is selected as key study.
