Description of key information
(from handbooks)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -165.2 °C
Additional information
Three literature sources provide consistent values, between -165.2 and -165°C. The average result of the two references considered as reliable (CRC and HSDB give respectively -165.12 and -165.2°C) is retained as key data.
