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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: In darkness at room temperature - Key result
- Melting / freezing pt.:
- < -100 °C
- Conclusions:
- The freezing point of the test item is < - 100°C.
- Executive summary:
The freezing point of the test item was determined with Differential Scanning Calorimetry (DSC) according to recognized guidelines (OECD Guideline 102 and EU Method A.1) and under GLP compliance. No deviations from the guidelines have been observed during the test.
No endothermic peak was observed during the DSC experiments.
Therefore, the freezing point of the test item is considered to be < - 100°C.
Reference
For the melting point, seven assays were performed. However, crucible position and software connection problems occured for the assays No. 1 to 5. The assays No. 6 and 7 were taken into account.
In these assay, the cooling phase was from about 25 °C to -100 °C at 10 °C/min. (Isotherm at about -100 °C for 15 min) and the heating phase was from -100 °C to 25 °C at 5 °C/min (Isotherm at 25 °C for 10 min).
In these 2 assays no freezing point of the test item was recorded down to -100 °C.
Description of key information
One reliable study (Klimisch 1) is available.
The freezing point of the test item was determined with Differential Scanning Calorimetry (DSC) according to recognized guidelines (OECD Guideline 102 and EU Method A.1).
The study was GLP compliant and no deviation from the guidelines was observed during the test.
No endothermic peak was observed during the DSC experiments.
Therefore, the freezing point of the test item is considered to be < - 100°C.
Key value for chemical safety assessment
Additional information
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.
