Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Remarks:
- The study was conducted using a relevant test method but not in compliance with any known quality system.
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- not specified
- GLP compliance:
- not specified
- Type of method:
- thermal analysis
- Remarks:
- Differential thermal analysis
- Melting / freezing pt.:
- -99.1 °C
- Atm. press.:
- 1 013 hPa
- Melting / freezing pt.:
- 174 K
- Atm. press.:
- 1 013 hPa
- Conclusions:
- A melting point value of -99.1°C (174 K) at 1013 hPa was determined for the substance using differential thermal analysis. The result is considered reliable.

Description of key information
Freezing point: -99.1°C at 1013 hPa
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -99.1 °C
Additional information
A freezing point value of -99.1°C (174 K) was determined for the substance using a differential thermal analysis method. The result is considered to be reliable and is selected as key study.
In available secondary sources to which reliability could not be assigned, freezing point values of -99°C, -102.2°C and -100.2°C at 1013 hPa were reported for the substance. The available values are consistent that the freezing point of the substance is <-20°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
