Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Type of method:
- capillary method
- Melting / freezing pt.:
- >= 53.6 - <= 58.3 °C
- Atm. press.:
- ca. 101.325 kPa
- Conclusions:
- The melting range of test substance is 53.6 °C ~ 58.3 °C.
Reference
The sample was a fine powdery solid, so it did not need to be ground into powder.
The approximate melting point of the sample was determined to be about 54.2 °C, so the start temperature was set to be below 44 °C (40 °C actually).
Results of the melting range are shown in the following table:
No. |
beginning temperatures [°C] |
final temperatures [°C] |
1 |
53.4 |
58.8 |
2 |
53.9 |
57.8 |
Mean |
53.6 |
58.3 |
Based on the test results, the melting range could be confirmed: 53.6 °C ~ 58.3 °C.
Description of key information
Melting range: 53.6 °C to 58.3 °C at ca. 101.325 kPa (OECD Guideline 102, capillary method)
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.
