- experimental study
- Adequacy of study:
- weight of evidence
- Study period:
- December 16, 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: OECD Guideline 102 (Melting point / Melting Range); EU Method A.1 (Melting / Freezing Temperature)
- Qualifier:
- according to guideline
- Guideline:
- other: OECD Guideline 103 (Boiling point/boiling range); EU Method A.2 (Boiling Temperature)
- Principles of method if other than guideline:
- The Differential Scanning Calorimetry (DSC) method was used for the evaluation of melting and boiling points of the test substance. Test was performed according to the SOP - SRT 028 protocol.
- GLP compliance:
- no
- Physical state at 20°C and 1013 hPa:
- solid
- Form:
- solid: particulate/powder
- Conclusions:
- The test substance is a solid at 20 °C and 1013 hPa.
- Executive summary:
Method
The test item melting point was determined using the Differential Scanning Calorimetry (DSC) according to the OECD Test Guidelines 102 and 103.
Results
Between 107 and 149 °C, there is a endothermic peak associated to the melting point, followed by a degradation starting from 220 °C; therefore boiling points is not recorded.
