Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of information:
experimental study
Adequacy of study:
key study
Study period:
2009-12-14 to 2010-06-07
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
OECD Guideline 102 (Melting point / Melting Range)
according to guideline
EU Method A.1 (Melting / Freezing Temperature)
GLP compliance:
yes (incl. QA statement)
Type of method:
differential scanning calorimetry
Key result
Melting / freezing pt.:
-3 °C
Remarks on result:
other: No melting was observed between -150°C and +50°C; the value reported is a glass transition temperature

Upon heating the test material has solidified amorphously and no other thermal effects were observed.

Under the conditions of the study, no melting point was determined but a glass transition was observed at -3 °C.
Executive summary:

The melting temperature of the substance was studied by differential scanning calorimetry (DSC) according to OECD Test Guideline 102 and EU test method A.1 “Melting/freezing temperature. The test material was cooled until -150°C and then heat until +50°C. No melting point was found between -150 and +50°C. A glass transition was observed at -3°C.


Description of key information

No melting/freezing point is available. A glass transition was observed at -3 °C.

Key value for chemical safety assessment
