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:
- 2015-01-21 to 2015-01-22
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted in accordance with a relevant test method and in compliance with a known quality system (ISO 17025).
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- GLP compliance:
- no
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- ca. -20 °C
- Atm. press.:
- 1 013 hPa
- Remarks on result:
- other: The freezing point of the substance was obtained to be <-20°C with a glass transition observed at -113°C
- Conclusions:
- A melting point of <-20°C at 1013 hPa was obtained for the substance with a glass transition observed at -113°C. The result is considered to be reliable.
Reference
The DSC measurements were performed twice. After cooling to -150°C at a rate of 2 K/min, the sample was heated to 50°C at a rate of 5 K/min. The cooling as well as the heating curve show only a glass transition, indicating that the test item had solidified amorphously.
No other thermal effect from crystallisation or melting was registered upon further heating.
Melting temperature: No melting point was found between -150 and +50°C under these conditions. A glass transition was observed at -113°C.
The DSC curves are attached.
Description of key information
Melting point: < -20°C at 1013 hPa (OECD 102)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -20 °C
Additional information
The freezing point of the substance has been determined using a differential scanning calorimetry (DSC) method in accordance with OECD Test Guideline 102 and in compliance with a known quality system (ISO 17025). Cooling of the sample was performed to -150°C at a rate of 2 K/min, then the test sample was heated to 50°C at a rate of 5 K/min. Under the conditions of the study, no melting point was found between -150°C and 50°C, but a glass transition was observed at -113°C. Therefore, the melting point of the substance was interpreted as < -20°C at 1013 hPa. The result is considered to be reliable and is selected as key study.
In available secondary sources to which reliability could not be assigned, a melting point value of approximately -80°C and a limit of < -78°C were reported for the substance.
