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:
- November 8, 2011 - January 11, 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- reference to same 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)
- Version / remarks:
- (2008)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- thermal analysis
- Remarks:
- (differential scanning calorimetry (DSC))
- Key result
- Remarks on result:
- other: Melting of the test substance was not observed at temperatures of < 400°C (< 673K)
- Conclusions:
- The melting temperature of the substance was determined using DSC in accordance with OECD 102 (1995), EU Method A.1 (2008) and according to GLP principles. As melting of the substance was not observed at temperatures of < 400°C (< 673K), the substance has no melting temperature (up to 400°C).
Reference
Preliminary test
No significant weight loss was observed. At 550°C the sample weight was similar to the start of the test. After the experiment, the test substance was unchanged i.e. no decomposition and/or evaporation was observed.
Main study
No effects related to melting of the test substance were observed. After the experiment, the test substance was unchanged.
Description of key information
The substance has no melting temperature (up to 400°C)
Key value for chemical safety assessment
Additional information
The melting temperature of the substance was determined using DSC in accordance with OECD 102 (1995), EU Method A.1 (2008) and according to GLP principles. As melting of the substance was not observed at temperatures of < 400°C, the substance has no melting temperature (up to 400°C).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
