Deviations:
no
GLP compliance:
no
Remarks:
Study was not performed under GLP, however the test facility was GLP-compliant.
Type of method:
differential scanning calorimetry
Key result
Melting / freezing pt.:
< -100 °C
Atm. press.:
1 021 hPa
Remarks on result:
other: No melting point down to -100°C

No thermal effects were observed in the temperature range from -100 to 25°C. It can be assumed that the test item has no melting or freezing point in this temperature range. Therefore the test item has no melting point down to a temperature of -100°C.

Conclusions:
The test item has no melting point down to -100°C at atmospheric pressure (1021 hPa), as determined by differential scanning calorimetry.
Executive summary:

Melting point was determined by differential scanning calorimetry according to OECD Guideline 102 and EU Method A.1 (2017). The study was not performed under GLP, however the test facility was GLP-compliant. The study is considered to be reliable without restrictions (Klimisch 1). The test item has no melting point down to -100°C at atmospheric pressure (1021 hPa).

Description of key information

The test item has no melting point down to -100°C at atmospheric pressure.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-100 °C
