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:
- 23 January - 25 March, 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. No deviation was reported. Test substance is adequately specified with isomer purity. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- UK GLP compliance programme (inspected on 05 February 2014 / signed on 07 October 2015)
- Type of method:
- method according to Siwoloboff
- Key result
- Boiling pt.:
- 274 °C
- Atm. press.:
- 1 036 mBar
- Decomposition:
- yes
- Executive summary:
The boiling point of the test substance was measured under GLP according to OECD 103 / EU A2 guideline, Siwoloboff (capillary) method. Two runs were performed, individual results were found to fall within accuracy, therefore the mean value is retained.
Slight darkening of the samples was noted on boiling, indicating possible decomposition.
The boiling temperature of the test substance was determined to be 274 °C, corrected to normal atmospheric pressure (1013 mbar).
Reference
The trial determination showed an approximate boiling point of 275 °C.
The results of duplicate boiling point determinations on test substance were as follows:
Barometric pressure: 1036 mbar

Slight darkening of the samples was noted on boiling, indicating possible decomposition.
The individual results were within the estimated accuracy of ± 2 °C.
Description of key information
Measured boiling point = 275°C under 1036 mbar; Corrected boiling point = 274°C to normal atmP (1013 mbar).
Slight darkening of the samples was noted on boiling, indicating possible decomposition.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 274 °C
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EU method, is available. It is considered as a key study. The result is retained as key data.
