Specific details on test material used for the study:
SOURCE OF TEST MATERIAL
- Lot/batch number of test material: 1903-3/2012
- Purity: not indicated
- Appearance: clear liquid
Key result
Melting / freezing pt.:
-0.7 °C
Remarks on result:
other: Atmospheric pressure not reported; ambient conditions are anticipated.

The first measurement revealed a freezing temperature of -0.8°C and the second measurement revealed a freezing temperature of -0.6°C.


The result is the mean of two runs

Conclusions:
The freezing temperature of the substance was concluded to be -0.7°C under ambient conditions.

Description of key information

The freezing point of the test substance under ambient conditions was determined to -0.7°C in a GLP study according to test method EC A.1 (Younis, 2013).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
