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
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Performed to guidelines, 2017
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- DSC analysis
- Principles of method if other than guideline:
- The water-based commercial sample was dried under a nitrogen purge to remove water prior to analysis.
- GLP compliance:
- not specified
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Physical State liquid
CAS # 83682-78-4
EU # 280-518-3
Sample ID 53461J16 - Key result
- Melting / freezing pt.:
- > -46 - < 10 °C
- Atm. press.:
- ca. 1 atm
- Decomposition:
- ambiguous
- Conclusions:
- Although appearing a waxy solid when dried, it appears to behave as a liquid at room-temperature with a melting range < 10 C
There was no clear melting transition.
It is also possible that there was retained water in the sample and the melting of water is partly responsible for the result.
The substance is supplied in water, so this figure is somewhat academic
Reference
Although appearing a waxy solid when dried, it appears to behave as a liquid at room-temperature with a melting range < 10 C
There was no clear melting transition.
Description of key information
Although appearing a waxy solid when dried, it appears to behave as a liquid at room-temperature with a melting range < 10 C
There was no clear melting transition.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 10 °C
Additional information
The waxy solid softens, but there is no clear melting transition; it is also possible that there was retained water in the sample and the melting of water is partly responsible for the result.
The substance is supplied in water, so this figure is somewhat academic
