Link to relevant study record(s)
- 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:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- differential scanning calorimetry
- Remarks on result:
- other: In the closed crucible, two endothermic phases were visible between approx. 43 °C – 75 °C and approx. 75 °C – 100 °C indicating a large melting range.
- Conclusions:
- Between 25 °C and 450 °C no definite melting could be observed by DTA/DSC method.
- Executive summary:
Melting point to test item EGGE 2806-1 was analyzed DTA/DSC.
Between 25 °C and 450 °C no definite melting could be observed. Two endothermic effects were visible between approx. 45 °C – 80 °C and approx. 80 °C – 100 °C indicating a large melting range. From approx. 160 °C to 255 °C another endothermic effect was observed, which goes over in two exothermic effects from 255 °C up to 450 °C very probably indicating decomposition of the test item.

- Key result
- Melting / freezing pt.:
- >= 90 - <= 100 °C
- Remarks on result:
- other: At approx. 100 °C sample transformed into a clear liquid, no solid particles were left
- Conclusions:
- Visual observation by capillary tube showed a melting range of approx. 90 - 100 °C to test item EGGE 2806-1.
- Executive summary:
Melting point to test item EGGE 2806-1 was analyzed via capillary tube (visual oberservation).
At about 40 °C the sample began to shrink partially. At about 90 °C the melting process of the shrunken sample started and was completed at approx. 100 °C ending with a clear liquid.
Melting range: approx. 90 – 100 °C

Description of key information
Between 25 °C and 450 °C no definite melting could be observed by DTA/DSC method.
Visual observation by capillary tube showed a melting range of approx. 90 - 100 °C to test item EGGE 2806-1.
