Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 03-25 April 2006
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. However, some critical experimental details are missing.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- signed 24 February 2006
- Type of method:
- differential scanning calorimetry
- Key result
- Boiling pt.:
- 251.7 °C
- Atm. press.:
- ca. 101 325 Pa
- Executive summary:
The boiling point of the test substance was determined under GLP according to EU A.2 guideline, using Differential Scanning Calorimetry (DSC).
Three runs were performed and found consistent, so the mean final temperature was retained.
The boiling temperature of test substance has been determined to be 251.7 ± 0.4 °C.

Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 251.7 °C
Additional information
A reliable experimental study, conducted according to a recognized EC method and under GLP, is available. Despite restrictions due to missing experimental details, it is considered as a key study, and the result is retained as key data.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
