Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2003-07-21
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:

- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- July 27, 1995
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- December 1992
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- thermal analysis

- Key result
- Melting / freezing pt.:
- < -70 °C
- Atm. press.:
- 101.325 kPa
- Conclusions:
- A limit freezing temperature of <-70°C at 101.3 kPa was determined for the test substance using a relevant test method and in compliance with GLP. The result is considered to be reliable.
Reference
A preliminary test was performed to check the approximate freezing temperature of the test substance. The test substance was cooled from room temperature to about -70°C. The sample was not frozen.
The determination of the freezing temperature with thermocouples showed no heat effect from which freezing can be deduced. Therefore, the phase transformation was determined visually.
Two main tests were performed to check the approximate freezing temperature of the test substance. At room temperature, the test item was clear and the agitator was stirring. The mixtures were cooled down to -70°C. At the end of the test, the test item samples were unaltered in appearance.
In conclusion, it was not possible to determine a freezing point or freezing range for the test substance under the conditions of the test. The freezing point or freezing range must be below -70°C.
Description of key information
Melting point: <-70°C at 1013 hPa (OECD 102)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -70 °C
Additional information
A limit freezing temperature of <-70°C at 1013 hPa was determined for the test substance in a study conducted according to OECD Test Guideline 102 and in compliance with GLP. The result is considered to be reliable and is selected as key study.
A limit value of <0°C was reported for the substance in a secondary source to which no reliability could be assigned.
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).
