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:
- 11 Jul - 12 Jul 2001
- Reliability:
- 1 (reliable without restriction)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- 92/69
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: Differential Thermal Analysis
- Key result
- Melting / freezing pt.:
- -30.3 °C
- Atm. press.:
- 101.325 hPa
- Conclusions:
- The test substance has a melting point of -30.3 °C.
- Executive summary:
In a GLP study according to EEC Method (92/69/EEC A.1), the melting point of the test substance was determined using differential thermal analysis(DTA). The mean melting point is -30.3 °C, derived from four test runs (2 closed crucibles, 2 open crucibles).
Reference
Validity criteria for the measurement of the melting point:
| Target condition according to guideline: | Actual condition according to the study: | Validity criteria met: |
| The mean of at least two measurements which are in the range of the estimated accuracy (up to 600K ± 0.5K up to) is reported as the melting temperature. | Mean of at least 2 measurments (-30.3/-30.3 °C) was used which are within estimated accuracy. | Yes |
| If the substance decomposes or sublimes before the melting temperature is reached, the temperature at which the effect is observed shall be reported. | No decomposition was reported | Yes |

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
