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:
- 12 May - 12 May 2006
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- 148 °C
- Atm. press.:
- 1 013.3 hPa
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- The test substance has a melting point of 148 °C.
- Executive summary:
In a GLP study according to EEC Method (92/69/EEC A.1) and OECD 102 (1995) test guidelines, the melting point/range of the test substance was determined using differential scanning calorimetry (DSC). The mean melting onset temperature is 148 °C, derived from three test runs at atmospheric pressure.
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 (± 0.5 K up to 600 K for this method) is reported as the melting temperature. | Mean of 3 measurments were reported and the accuracy accounted to ±0.67 which is slightly higher than the range of estimated accuracy of ± 0.5 K. However according to the guideline the real accuracy dependent on type of instrument and on degree of purity of the substance. Therefore, the obtained mean value is considered valid. | 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.
