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:
- 2016-12-05
- 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:
- 27. July 1995
- 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:
- other: Metal block capillary method
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- ca. 148 °C
- Remarks on result:
- not determinable
- Conclusions:
- At about 148 °C the colour of the test item changed and no clear melt could be observed. The test item did not melt, but decomposed.
- Executive summary:
The test was carried out according to OECD guideline 102 and EC method A.1. Capillary tubes filled with the test item were heated in a metal block. The test item starts to decompose at 148 °C, hence no melting point could be observed.
Reference
- Preliminary test: At about 155 °C the colour of the test item started to change from light yellow to blue-green including air bubbles. The test item did not melt, but decomposed.
- Main test: At about 148 °C the colour of the test item changed and no clear melt could be observed. The test item did not melt, but decomposed.
Description of key information
For this endpoint one experimental study is available, which has been conducted according to OECD 102, metal block capillary method. It was observed that the test item starts to decompose at 148 °C, hence no melting point could be observed.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 148 °C
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.
