Method
The melting point was determined using the Differential Scanning Calorimetry (DSC) according to the OECD guidelines 102 and 103.
Results
Melting of the substance occurs between 110 and 157 °C, followed by decomposition starting at ca. 246 °C.
Reference
Initial weight of sample: 4.7210 mg
Final weight after DSC: 2.5950 mg
Melting between 110 and 157 °C, followed by decomposition starting at ca. 246 °C.
Description of key information
Melting of the sample between 110 and 157 °C, with onset at 126.8 °C and enthalpy of -32.3 J/g.
Sample decomposition starting at ca. 246 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 126.8 °C
Additional information
Thermal analysis based on Differential Scanning Calorimetry.
