Description of key information

Key value for chemical safety assessment

Additional information

Three measured melting point values from the same author (Haas, 2017) are available for the substance.

A melting point value of <-80.0°C at 1013 hPa was determined for the substance using a Differential Scanning Calorimetry (DSC) method in accordance with OECD Test Guideline 102. The value is considered to be reliable and is selected as key value. Additionally, a melting point of <-50.0°C at 1013 hPa was determined for the substance using a cloud point method in accordance with the ISO 3015 test method and a melting point of <-50.0°C at 1013 hPa was determined for the substance using a pour point method in accordance with the OECD Guideline 102.

All three studies were conducted in compliance with a known quality system (ISO 9001:2008).
