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:
- 25 April 2016 - 26 April 2016
- 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)
- Version / remarks:
- 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7200 (Melting Point / Melting Range)
- Version / remarks:
- 1996
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: ISO 1392 (Determination of Crystallizing Point)
- Version / remarks:
- 1977
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- method to determine freezing temperature
- Key result
- Melting / freezing pt.:
- < -43 °C
- Conclusions:
- The freezing temperature of the test substance was < –43°C at atmospheric pressure.
- Executive summary:
The freezing temperature of the test substance was determined to be < -43°C at atmospheric pressure. No typical effect indicating a phase transition was observed. At the end of the measurement, the test item was a highly viscous liquid. This study is reliable without restriction (Klimisch 1) as it was performed according to guidelines OECD 102, EU A.1, OPPTS 830.7200 and ISO 1392. The study was not GLP-compliant, however the test facility is GLP-compliant.

Description of key information
The freezing temperature of the test substance was determined to be < -43°C at atmospheric pressure.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -43 °C
Additional information
This freezing temperature was determined in a non-GLP study performed according to guidelines OECD 102, EU A.1, OPPTS 830.7200 and ISO 1392 (2016). The study is considered to be reliable without restriction (Klimisch 1). No typical effect indicating a phase transition was observed. At the end of the measurement, the test item was a highly viscous liquid.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
