Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: The test has been performed following official guidelines and completely assessed the end point.
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- GLP compliance:
- no
- Type of method:
- thermal analysis
- Remarks:
- DSC
- Atm. press.:
- ca. 1 atm
- Decomposition:
- yes
- Decomp. temp.:
- > 267 - < 368 °C
- Conclusions:
- The substance melting point was determined by DSC according to OECD 102. The decomposition of the substance was observed with onset temperature equal to 310.6°C.
- Executive summary:
The substance melting point was tested by thermoanalysis (DSC) according to OECD 102. water evaporation occured between 25 - 150°C,
followed by substance an endothermic effect between 242 -263°C and decomposition between 267 - 368°C.
The decomposition onset is 310.6°C with an enthalpy energy equal to 173.7 J/g.
Reference
Between 25 -150°C water evaporation occurs, followed by substance an endothermic effect between 242 -263°C and decomposition between 267 - 368°C. The decomposition onset is 310.6°C with an enthalpy energy equal to 173.7 J/g.
Description of key information
Thermal decomposition > 267 °C (onset 310.6 °C)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 310.6 °C
Additional information
The melting point of the substance has been determined with DSC (differential scanning calorimetry) showed the thermal decomposition in connection with the loss of the mass starting at the temperature of 242 °C. The enthalpy of the decomposition between 267°C and 368 °C is 173.7 J/g.
No endothermic peak corresponding to melting and boiling of the test substance was recorded in the tested temperature range from 25 °C to 600 °C.
