Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 31 July 2006
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Comparable to guideline study (EU A.1) with acceptable restrictions
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Principles of method if other than guideline:
- DSC measurement according to company guideline.
- Type of method:
- thermal analysis
- Decomposition:
- yes
- Decomp. temp.:
- ca. 296 °C
- Conclusions:
- The test item starts to decompose at ca. 296°C.
- Executive summary:
The thermal behaviour of the test substance was investigated by Differential Scanning Calorimetry (DSC). The test substance starts to decompose at ca. 296 °C without prior melting or boiling.
Reference
Two measurements were conducted. No endothermic effects (melting/boiling) were observed.
The test substance starts to react with the oxygen left in the sealed glass vial at ca. 245 °C (mean energy from 2 measurements 18.5 J/g).
The decomposition peak appears at 296 °C (mean energy from 2 measurements 98 J/g).
Description of key information
The thermal behaviour of the test substance was investigated by Differential Scanning Calorimetry (DSC). The test substance starts to decompose at ca. 296 °C without prior melting or boiling.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 296 °C
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.
