- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:

- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- 31. May 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- 7.01 °C
- Decomposition:
- no
- Remarks on result:
- other: melting point
- Conclusions:
- The melting point of the test substance was found to be: 7.01 ± 0.05 °C (280.16 ± 0.05 K).
- Executive summary:
The determination of the test substance melting point was performed via DSC (differential scanning calorimetry) according to OECD 102.
The crucible containing the test item was cooled down from room temperature to -65°C and then heated again to 35°C using a heating rate of 10 K/min.
In all runs one event was detected. The event is endotherm and corresponds to the melting point.
The melting point of the test substance was found to be: 7.01 ± 0.05 °C (280.16 ± 0.05 K). This value is the mean of two independent determinations.
Results pre-test:
Test material was nearly frozen at 3.5°C, and frozen at -20 and -80 °C.
Main study:
In all runs one event was detected. The event is endotherm and corresponds to the melting point. For the calculation of the value of the mean the results of the first and third determination are taken. As the difference between the two determinations was below 0.5 K the result can be considered valid.
