Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 26 January 2016 - 26 February 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- thermal analysis
- Melting / freezing pt.:
- > 400 °C
- Conclusions:
- The test material was determined to have a melting temperature greater than 400°C (723 K).
Reference
The test item was solid and white at the start and at the end of the measurement.
No melting point according to the criteria described in the guideline could be observed up to 400 °C
Description of key information
Melting point: > 400°C (OECD 102, A.1., capillary method).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 400 °C
Additional information
The melting point of the substance was determined by usingcapillary method.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
