Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
January 20, 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)
Principles of method if other than guideline:
The Differential Scanning Calorimetry method was used for the evaluation of melting and boiling points of the test substance. Test was performed according to the SOP - SRT 028 protocol.
GLP compliance:
no
Type of method:
thermal analysis
Key result
Decomposition:
yes
Decomp. temp.:
> 237 - < 403 °C

Between 40 -230 °C, there is a endothermic peak associated to the release of water/ solvent, followed by a exothermic peak related to degradation between 237 - 403 °C (onset 301.75 °C enthalpy = 221.30 J/g)

Conclusions:
The test substance decomposes before melting at temperature between 237 and 403 °C
Executive summary:

Method

The test was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method for the analysis.

Result

Between 40 - 230 °C, there is a endothermic peak associated to the release of water/ solvent, followed by a exothermic peak related to  degradation between 237 and 403 °C (onset 301.75 °C enthalpy = 221.30 J/g).

Description of key information

The substance decomposes before melting/boiling between 237 and 403°C 

Key value for chemical safety assessment

Additional information

The Melting Point analysis was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method for the analysis. Between 40 - 230 °C, there is a endothermic peak associated to the release of water/ solvent, followed by a exothermic peak related to degradation between 237 - 403 °C
