- Conclusions:
- The test item is a solid which decomposes before melting.
- Executive summary:
Method:
Differential Scanning Calorimetry (DSC) according to the OECD Test Guidelines 102 and 103.
Results:
Between 25 and 160°C there is a release of imbibition/crystallization water. Between 244-423°C it is registered an exothermic effect (onset 282.3°C, enthalpy = 1673 J/g).
Conclusion:
The test item is a solid which decomposes before melting.
- Endpoint:
- melting point/freezing point
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- Calculation of the melting point by MPBPVP v1.43
- Type of method:
- other: calculation

Description of key information
Decomposition before melting.
Calculated Melting Point = ca. 350°C
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 350 °C
Additional information
The substance decomposes before melting at temperature above 244 °C (test according OECD 102 Guideline).
