Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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: GLP Guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Type of method:
thermal analysis
Remarks:
Differential Thermal Analysis (DTA) / Differential Scanning Calorimetry (DSC)
Decomp. temp.:
> 140 - < 450 °C

From -100 °C up to 450 °C no melting point could be observed. Between approx. 140 °C and approx. 215 °C an exothermic reaction could be observed which could indicate decomposition of the test item. Between approx. 220 and approx. 290 °C additional endothermic effects were detected. From approx. 330 °C up to approx. 450 °C a further exothermic effect is visible. After the heating process a brownish residue remains in the crucible which indicates decomposition of the test item.

Conclusions:
From -100 °C up to 450 °C no melting point could be observed.
Executive summary:

According to EU Method A. 1 no melting point was observed from -100 °C up to 450 °C. Between approx. 140 °C and approx. 215 °C an exothermic reaction could be observed which could indicate decomposition of the test item. Between approx. 220 and approx. 290 °C additional endothermic effects were detected. From approx. 330 °C up to approx. 450 °C a further exothermic effect is visible. After the heating process a brownish residue remains in the crucible which indicates decomposition of the test item.

Description of key information
