Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
April 20, 2015
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
GLP compliance:
no
Type of method:
thermal analysis
Remarks:
Differential Scanning Calorimetry
Decomposition:
yes
Decomp. temp.:
> 258 - < 402 °C

Between 25 -150 °C, there is a endothermic peak associated to the release of water/ solvent, followed by a exothermic peak, related to the degradation, between 258 - 402 °C.

Conclusions:
The test substance decomposes before melting at temperature between 258 - 402 °C.
Executive summary:

Method

The test was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method for the analysis.

Results

Between 25 -150 °C, there is a endothermic peak associated to the release of water/ solvent, followed by a degradation between 258 and 402 °C (onset 302 °C, enthalpy = 683.74 J/g).

Description of key information

The substance decomposes before boiling between 258 - 402 °C

Key value for chemical safety assessment
