Description of key information

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-50 °C

Additional information

Based on the information provided in assessment reports and handbooks (WoE Klimisch 4), the melting point ranges from -52 to -50°C. No further information was provided. Since the data from these documents are typically reviewed and reliable, the reported melting point is considered reliable even if experimental details were not provided. The values are all within a close range providing Further evidence that these values are correct within the typical error ranges.

For the further risk assessment, a melting point of - 50 °C will be used.
