Result of DSC method

The uncorrected boiling temperature (peak onset at 244.0°C) of the DSC/TG measurement corresponds to the values of the capillary tube/photocell method very closely.

Conclusions:
A boiling point value of 245°C at 1013 hPa was determined for the substance in accordance with a relevant test method and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable.

Description of key information

Boiling point: 245°C at 1013 hPa (EU Method A.2)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
245 °C

Additional information

A measured boiling temperature of 245°C (518.2 K) at 1013 hPa was determined for the submission substance using a photocell detection method in accordance with EU Test Method A.2 and in compliance with a known quality system (ISO 9001:2008). In addition to the photocell detection method, the boiling point of the substance was determined using a DSC method. A boiling point value of 244°C (uncorrected boiling temperature) was obtained for the substance. The results are considered to be reliable.
