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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

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
- Study period:
- February and March 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method. No deviation affected the quality of the study. The substance is considered to be adequately characterised with composition. Therefore validation applies without restrictions.
- Qualifier:
- according to guideline
- 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:
- Regulation (EC) n°440/2008
- Deviations:
- no
- GLP compliance:
- no
- Remarks:
- not required for physchem data, unless relating to CLP
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- < -80 °C
- Atm. press.:
- 101.6 kPa
- Executive summary:
The test substance was first cooled down to -80°C, then the melting point was determined according to OECD102/EU A.1 guideline, using Differential Scanning Calorimetry method.
Two main runs were performed, under nitrogen flow. No phase transition was observed during both cooling and heating phases.
The melting point of the test item is stated as lower than -80 °C.
Reference
Assay 1: < -80 °C (101.6 kPa)
Assay 2: < -80 °C (101.6 kPa)
Mean: < -80 °C
No melting and no freezing points are detected with measurements at the lowest possible DSC temperature. Only a threshold value of below -80 °C can be provided.
Description of key information
No freezing or melting observed down to -80°C.
Key value for chemical safety assessment
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method, is available. It is considered as a key study. Since the result is expressed as a limit value, it cannot be used as key data (no "<" sign allowed).
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
