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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 2015
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- not applicable
- GLP compliance:
- no
- Type of method:
- thermal analysis
- Remarks:
- Differential Thermal Analysis (DTA) / Differential Scanning Calorimetry (DSC)
- Melting / freezing pt.:
- 206 °C
- Decomposition:
- yes
- Decomp. temp.:
- >= 240 - < 380 °C
- Remarks on result:
- other: No pressure reported
- Conclusions:
- The melting temperature of the substance is in the range of 204 and 207 °C and no pressure was reported.
- Executive summary:
A differential thermoanalysis method (DTA) was used to determine the melting point which conforms with the procedure Test method A.1, "Determination of the melting point", described in the EC-Guideline. A melting range of the substance between approx. 204 to 207 °C could be observed. After the melting of the test item an exothermal phase could be observed between around 240 and 380 °C.
Reference
RESULT:
- A melting point between 204 and 207 °C could be observed due to the detected endothermal effect
- After the melting of the test item an exothermal phase could be observed between around 240 and 380 °C
- Up to the decomposition of the test item no definite boiling point was observed
Description of key information
The melting temperature of the substance is in the range of 204 and 207 °C and no pressure was reported. In another study the DSC traces exhibit only the melting endotherm with an onset temperature between 207.4 °C and 207.9 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 206 °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.
