- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- GLP compliance:
- not specified
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- Batch: XP3646
Appearance/Physical State: White/Pale yellow semi-solid - Key result
- Melting / freezing pt.:
- > -27 - < 28 °C
- Conclusions:
- The melting temperature of the test item has been determined to be over the range -27 to 28 ˚C ( 246 to 301 K) .
- Executive summary:
The test result was based on the range over which the test item melted. This was because freezing temperatures, although consistent in this case, are susceptible to being lower than the melting temperature due to super cooling. Additionally, it was not possible to accurately determine where the freezing event ended. The melting temperature gives an overall more accurate result but the freezing temperature is included for additional information.

- > 40 - < 80 °C
- Remarks on result:
- not determinable
- Remarks:
- No melting pointg occured over this heating range.
- Conclusions:
- No melting point could be determined.
- Executive summary:
Using two gradients no significant melt was observed and therefore could not be reported. Observations from vapour pressure testing on the same test item, gave an indicative melt of between 40 -80 C, but the accuracy of this measurements is not known. Substance is polymeric in nature and such may exhibit differing behaviour based on the different crystalline forms and the application of different heating rates during testing. Therefore it was not posisble to determine melting point using this test.

Description of key information
The melting/freezing temperature is defined as the point at which phase transition from solid to liquid state (or vice versa) at normal atmospheric pressure takes place. As the phase transition of many substance takes place over a large temperature range, it is often described as a melting/freezing range. During thermal analysis the peak width of an endothermic reaction also depends on sample amount and heating rate. Therefore, the onset point of the relevant endothermic peak is usually stated as the melting temperature. Where the endothermic peaks/effects are poorly defined, a range was stated in the result section.
The melting temperature of the test item has been determined to be over the range -27 to 28 ˚C ( 246 to 301 K) in one study using differential scanning calorimetry method.
In another study using two gradients no significant melt was observed and therefore could not be reported. Observations from vapour pressure testing on the same test item, gave an indicative melt of between 40-80 °C, but the accuracy of this measurements is not known. Substance is polymeric in nature and such may exhibit differing behaviour based on the different crystalline forms and the application of different heating rates during testing. Therefore it was not posisble to determine melting point using this test.
In conclusion it is not tehnically possible to report a single melting point for this test item.
