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:
- not specified
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The analysis was performed using Differential Scanning Calorimetry (DSC). The sample was sealed in a preweighed aluminum hermetic T-zero pan and the sample weight was recorded. The sample was loaded into the DSC and cooled under a nitrogen purge to -70°C. The sample was then heated at 20°C/min to 100°C. A broad melting endotherm was recorded and reported.
- GLP compliance:
- not specified
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- ca. 20 - ca. 39 °C
- Atm. press.:
- ca. 1 atm
- Remarks on result:
- other: A broad melting endotherm was observed starting at -55°C and continuing to 60°C. Two melting peaks were observed at 20°C and 39°C.
- Conclusions:
- Under the study conditions, the melting point range of the test substance was determined to be 20 to 39°C.
- Executive summary:
A study was conducted to determine the melting point of the test substance using Differential Scanning Calorimetry (DSC) method. The sample was sealed in a preweighed aluminum hermetic T-zero pan and the sample weight was recorded. The sample was loaded into the DSC and cooled under a nitrogen purge to -70°C. The sample was then heated at 20°C/min to 100°C. A broad melting endotherm was observed starting at -55°C and continuing to 60°C; whereas two melting peaks were observed at 20°C and 39°C. Under the study conditions, the melting point range of the test substance was determined to be 20 to 39°C (ADM, 2019).
