Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Test dates: April 17 to July 4, 2013
- 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, but experimental details are missing. The substance is adequately characterised. Therefore validation applies with restrictions.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- GIPC, opinion dated 21 December 2012
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Storage condition of test material: Stored at room temperature, protected from direct sun light.
- Key result
- Boiling pt.:
- 248.9 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- no
- Executive summary:
The boiling point of the test substance was determined under GLP according to EU A2 guideline, using Differential Scanning Calorimetry (DSC) method.
The mean of four consistent determinations was retained.
The boiling temperature of test substance was determined to be 248.9°C, at ca atmospheric pressure.
Reference
Four successive tests were retained:
| Test No. | Onset temperature |
| 1 | 249.1°C |
| 2 | 248.7°C |
| 3 | 249.1°C |
| 4 | 248.8°C |
| Mean +/- SD | 248.9 +/-0.2°C |
The validity criteria for repeatability were fulfilled: the standard deviation within the four replicate assessments did not exceed 0.5 °C.
Therefore the average value is retained as final result.
Description of key information
Experimental boiling point = 248.9°C (atmP not specified).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 248.9 °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 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. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
