Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 20 November - 01 December 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study

- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- 2008
- Deviations:
- no
- Principles of method if other than guideline:
- Not applicable
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Inspected on 4,5 and 6 July 2016/ Signed on 10 January 2017
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- < -20 °C
- Atm. press.:
- ca. 1 017 hPa
- Decomposition:
- no
- Conclusions:
- The melting point of test item was stated as: <-20°C (253.15 K).
- Executive summary:
The study was performed in order to determine the melting point of test item according to OECD 102, resp. EU A.1 guideline, using the DSC method.
The melting point of test item is stated as: <-20°C (253.15 K).
Reference
Results of trials 1 and 2 were not used as the peak was not exploitable.
No melting point was detected for trials 3 and 4 until -20°C. The melting point was stated as : <-20°C.
The crucible was visually checked after the determination: By opening the crucible, no sign of decomposition was observed.
Description of key information
The melting point was stated as: <-20°C (253.15K)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -20 °C
Additional information
A fully reliable experimental study, conducted according to OECD 102/ EU A1 guideline is available.
It is considered as a key study, and the result is retained as key data.
