Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 19-20 February 2018
- 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 test substance is adequately characterised. Therefore full validation applies.
- Reason / purpose for cross-reference:
- reference to same study
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- 2008
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Inspected on 13 and 14 October 2014/ Signed on 8 April 2015
- Type of method:
- method according to Siwoloboff
- Key result
- Boiling pt.:
- 202.5 °C
- Atm. press.:
- >= 99 734 - <= 99 760 Pa
- Decomposition:
- yes
- Decomp. temp.:
- >= 188 °C
- Conclusions:
- The determination of the boiling point of test item was performed following the Siwoloboff Method.
First sign of possibly decomposition indicated by a colourless condensate and colour change were observed since 188°C.
Therefore the boiling point of test item should be stated as: 202.5 ± 1.6 °C (475.6 ± 1.6 K) under decomposition of the test item.
This value is the mean of two independent determinations without Sydney-Young correction. - Executive summary:
The study was performed in order to determine the boiling point of test item according to OECD 103, resp. EU A.2, guideline, using the Siwoloboff method.
The boiling point of test item should be stated as: 202.5 ± 1.6 °C (475.6 ± 1.6 K) under decomposition of the test item.
