Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Valid method
Principles of method if other than guideline:
Differential thermal analysis (DTA)
Type of method:
thermal analysis
Decomp. temp.:
>= 310 °C

No melting point observed. Decomposition (with an energy of -140 J/g) starting at 310 °C.

The test substance decomposes at 310 °C instead of melting.
Executive summary:

The thermal behaviour of the test substance was determined with Differential Thermal Analysis (DTA) measurements. No melting was observed. Decomposition started at 310 °C.

Description of key information

No melting was observed. Decomposition started at 310 °C.

Key value for chemical safety assessment
