- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- 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:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- < -90 °C
- Atm. press.:
- 1 021 hPa
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: No melting/freezing observed at -90 °C (183 K)
- Conclusions:
- The substance has a melting point of below -90 °C at 1021 hPa.
- Executive summary:
The melting point of the substance was determined in a study in accordance with OECD TG 102 (differential scanning calorimetry (DSC)) and in compliance with GLP criteria. The test substance is evaluated from the DSC curve as the extrapolated onset temperature of the endothermic melting peak. Freezing and or melting of the test substance was not observed at -90 °C (183K). Therefore, the melting temperature of the test substance lies beyond the scope of this test. As a conclusion, the melting point is determined at <-90 °C at 1021 hPa.
Reference
Freezing and or melting of the test substance was not observed at -90 °C (183K). Therefore, the melting temperature of the test substance lies beyond the scope of this test. The atmospheric pressure was 1021±1 hPa.
Description of key information
The melting point is determined at <-90 °C at 1021 hPa.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -90 °C
Additional information
The melting point of the substance was determined in a study in accordance with OECD TG 102 (differential scanning calorimetry (DSC)) and in compliance with GLP criteria (NOTOX BV, 2010). The test substance is evaluated from the DSC curve as the extrapolated onset temperature of the endothermic melting peak. Freezing and or melting of the test substance was not observed at -90 °C (183K). Therefore, the melting temperature of the test substance lies beyond the scope of this test.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
