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:
- 05 December 2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- non-CLP
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- GLP compliance:
- no
- Type of method:
- other: see description
- Boiling pt.:
- 341.6 °C
- Atm. press.:
- 1 034 mBar
- Decomposition:
- no
- Remarks on result:
- other: At temperatures higher than 341.9ºC there was significant darkening of the liquid substance, indicating oxidation of the test material. It was noted that at 403±2°C there was rapid bubble formation and apparent further boiling.
- Remarks:
- This might indicate the boiling point of the oxidised material or the presence of impurities in the sample.
- Conclusions:
- The boiling point of the substance is 341.6°C

The boiling point was based on the findings in run 3 and 4.
The viscous nature of the melted sample made it difficult to determine the endpoint of boiling and so several attempts were made to determine the correct value range and to confirm observations. The variation of extremes between the observed final boiling points was ±3°C. This exceeds the guideline range of ±2°C, but as this guideline value is intended for mono-constituent materials, the range of ±3°C is deemed acceptable in this case given that the substance is a UVCB.
The determined onset of boiling was also considerably below the determined boiling point.
Description of key information

Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 341.6 °C
