Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- March 17 to April 04, 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- The study was conducted according to an internationally recognised method, and under GLP. The substance is considered to be adequately characterised. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Version / remarks:
- dated 27. Jul. 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- dated 31. May 2008
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- inspected on 29 and 30 November 2010 / signed on 11 April 2011
- Type of method:
- method according to Siwoloboff
- Key result
- Boiling pt.:
- > 407 °C
- Atm. press.:
- 1 013 hPa
- Decomposition:
- no
- Conclusions:
- The boiling point of the test item was stated as > 407 °C (680.2 K) using Siwoloboff method.
No signs of decomposition were observed when the substance is heated up to 407°C. - Executive summary:
A study was conduted to determine the initial boiling point of the test substance under GLP according to EU Method A.2 and OECD 103 following the Siwoloboff method.
No boiling point could be detected up to a temperature of 407 °C and no change in the test item appearance was detectable visually after cooling down.
Therefore, the boiling point of the test substance was stated as > 407 °C (680.2 K), limit of the applicability domain of the Siwoloboff method.

No boiling point could be detected up to a temperature of 407 °C following the SIWOLOBOFF method.
After cooling down, no change in the test item appearance was detectable.
Therefore, the boiling point of test item should be stated as > 407 °C.
Description of key information
The boiling point of the test item has been stated as > 407 °C (680.2 K) using the Siwoloboff method.
No signs of decomposition were observed when the substance is heated up to 407°C.
Key value for chemical safety assessment
Additional information
A reliable experimental study, conducted according to a recognized OECD/EC, following the Siwoloboff method and under GLP, is available. It is considered as a key study. However, no boiling point could be determined up to 407°C (680.2K, limit of applicability domain of Siwoloboff method) and no key value can be retained as key data for purpose CSA.
