- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Physical state: Clear, colourless liquid.
Storage conditions of test material: Room temperature, in the dark, under nitrogen. - Key result
- Boiling pt.:
- 279 °C
- Atm. press.:
- 97.26 kPa
- Decomposition:
- no
- Executive summary:
The boiling point of the test substance was determined under GLP by differential scanning calorimetry (DSC) using the procedure specified in ASTM E537-86 and according to EU Method A.2 (Boiling Temperature).
Two main runs were performed under nitrogen atmosphere, and the mean final temperature was retained.
The boiling temperature of test substance has been determined to be 552 ± 0.5 K (279 °C) at an atmospheric pressure of 97.26 kPa, under nitrogen.

Description of key information
Boiling point = 279 °C under inert (nitrogen) atmosphere and 97.26 kPa (not corrected).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 279 °C
Additional information
A fully reliable experimental study, conducted according to a recognized method (EU A2) and under GLP, is available. Therefore, it is considered as a key study, and the result is retained as key value.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
