Description of key information
A K1, GLP-compliant study was performed according to a method compatible with OECD guideline 102 and EU Method A.1. The freezing point of the test substance was determined to be <-20 °C or < 253 K (Covance, 2019).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -20 °C
Additional information
The freezing point was determined to be <-20 °C.
