Key result
Melting / freezing pt.:
< -20 °C
Decomposition:
no
Sublimation:
no
Remarks on result:
other: Mean of at least two measurements which are in the range of the estimated accuracy

The sample did not freeze at -20.0°C.

Conclusions:
The freezing point of the substance is determined to be < -20°C since the sample did not freeze at -20.0°C.

Description of key information

A K1 GLP study was performed according to OECD guideline 102 and EU Method A.1. The freezing point of the test substance was found to be <-20 °C (Younis, 2017).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-20 °C

Additional information

The freezing point of the test item was determined to be <-20°C.
