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:
- from 21/07/2017 to 28/09/2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- Test method is according to the OECD guideline 102. Test substance adequately specified. Reliability applies with restrictions, as it is not conducted under GLP conditions
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM E 537-86
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- - Storage condition of test material: between 15 and 35 ºC, light protected
- Key result
- Melting / freezing pt.:
- 5.8 °C
- Atm. press.:
- 1 atm
- Decomposition:
- no
- Remarks on result:
- other: Accuracy: +/- 0.5ºC
- Conclusions:
- The freezing point of the test material was determined to be 5.8 ± 0.5 °C at atmospheric pressure
- Executive summary:
The melting point of the test substance was determined according to OECD guideline 102, DSC method. Two separate measurements were performed, showing an average melting point of 5.8 ± 0.5 °C at atmospheric pressure.

Description of key information
Freezing (i.e. liquid-solid transition) occurs at 5.8 °C at atmospheric pressure (DSC, OECD 102).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 5.8 °C
Additional information
A reliable experimental study, conducted according to OECD guideline, DSC method, is available. Despite acceptable restrictions, it is considered as a key study. The result is retained as key data.
