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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 24 December 2015 to 22 March 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Guideline study under GLP, based on the results only a range could be defined
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7200 (Melting Point / Melting Range)
- GLP compliance:
- yes
- Type of method:
- other: differential scanning calorimetry
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- > 225 °C
- Remarks on result:
- other: at atmospheric pressure
- Remarks:
- the melting point could not deteremined due to evaporation and decomposition of the components
- Conclusions:
- The melting temperature of the substance could not be determined
- Executive summary:
Using the differential scanning calorimetric method the melting point of the substance could not deteremined due to evaporation and decomposition of the components
Reference
pre-test: decomposition (reduction of weight by 25% at 352 °C)
exp 1: glass transition between -58.17°C ; melting at 52.24°C (additional endothemic peak at ca 90 °C)
exp 2:
first cycle: glass transition at -58.22 °C ; melting at 52.38°C (additional endothermic peak at 85 °C)
second cycle: glass transition at -24.93 °C ; melting at 75.35°C ( no additional exothermic peak seen)
Description of key information
Using the differential scanning calorimetric method the melting point could not be determined due to evaporation and decomposition of the components
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.
