- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- -36 °C
- Atm. press.:
- 102.3 kPa
- Conclusions:
- The melting temperature of the substance was determined as -36 °C (237 K) at atmospheric pressure (102.3 kPa).
- Executive summary:
The melting point was measured by Differential Scanning Calorimeter (DSC) using the procedure specified in Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995 and EU Method A.1.
The melting temperature of the test material was determined as -36 °C (237 K) at atmospheric pressure (102.3 kPa).
Reference
The melting temperature of the substance was determined by DSC. The melting temperature of the test substancewas determined as -36 °C (237 K) at atmospheric pressure (102.3 kPa).

Additional information
In a single key study, the melting point was measured by Differential Scanning Calorimeter (DSC) using the procedure specified in Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995 and EU Method A.1.
The melting temperature of the test material was determined as -36 °C (237 K) at atmospheric pressure (102.3 kPa).
