- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study

- key study
- Study period:
- 2017-06-27 to 2018-03-15
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:

- Qualifier:
- according to guideline
- Guideline:
- other: OECD Guideline 103 Boiling point
- Version / remarks:
- 1995-07-27
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- >= 70 - <= 89 °C
- Conclusions:
- The melting point of N,N'-[(methylimino)bis(trimethylene)]bis(stearamide) was determined to be in a range of 70 to 89 °C, using differential scanning calorimetry.
- Executive summary:
A study on differential scanning calorimetry according to OECD Guideline 103 (27 July 1995) was conducted with N,N′-[(methylimino)bis-(trimethlene)]bis-(stearamide).
The heating phase covered a range from room temperature to 500 °C. During the heating phase endothermic effects were observed in two temperature ranges. The first endothermic effect can be assigned to the melting of the test item. The test item showed a second endothermic signal in the temperature range of approx. 350 -470 °C.
No further thermal effects were observed up to the test end temperature of 500 °C.Melting of N,N′-[(methylimino)bis-(trimethlene)]bis-(stearamide) was observed in a range of 70 to 89 °C.
