Description of key information
The freezing temperature of the test substance was determined to be 39.7 °C in a non-GLP test according to OECD 102.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 39.7 °C
Additional information
The freezing temperature of the test substance was determined to be 39.7 °C in a non-GLP test according to OECD 102.
This value can be confirmed by an experimental value stated in the database of the EPIWIN program (41.5 °C) and one from the GESTIS database (melting range of 38 - 41 °C).
