Description of key information

-3 °C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-3 °C

Additional information

Pour point determined according to OECD 102. Older lower quality data support the fact that the melting temperature is low (< -23.3 °C). Handhook data (+ 38 °C ) is disregarded because of inconsistency.
