DSC:

The measured onset temperature of the boiling peak (165.9°C at 964.8 hPa) confirms the boiling temperature values of the capillary tube / photocell method.

Conclusions:
A boiling point value of 167.3°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: 167.3°C at 101.3 kPa (OECD 103)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
167.3 °C

Additional information

A measured boiling point value of 167.3°C (440.5 K) at 1013 hPa was determined for the substance using a photocell detection method in accordance with OECD Test Guideline 103 and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable and is selected as key study.

The key study is supported by boiling point values of 165 –166°C and 168.8°C at 1013 hPa which were reported for the submission substance in handbooks or collections of reliable data which have been subject to peer-review and in which the original data sources are traceable.

In available secondary sources to which reliability could not be assigned, boiling point values of 165.5 – 169°C at 1013 hPa were reported for the substance. The supporting studies are in good agreement with the key study.
