Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
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:
Test was performed according to the SOP - SRT 028 protocol.
GLP compliance:
no
Type of method:
differential scanning calorimetry
Decomposition:
yes
Decomp. temp.:
> 210 - < 402 °C
Sublimation:
no

Release of water/solvent occurs between 60 -187°C, followed by an exothermic decomposition between 210 and 402°C (onset 300.1°C, enthalpy 446.9 J/g).

Conclusions:
Test substance decomposes before melting at temperature between 210 and 402°C (onset 300.1°C enthalpy = 446.9 J/g)
Executive summary:

Method:


DSC analysis according to OECD guideine 102.


Result:


Release of water/imbibition solvent occurs between 60 - 187°C, followed by a exothermic peak related to decomposition between 210 and 402°C (onset 300.1°C, enthalpy = 446.9 J/g)

Description of key information

No melting occurs up to 450°C. The substance decomposes between 210 and 402°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
500 °C
