Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
October 08, 2015
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Test conducted according to internationally accepted testing guidelines.
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
not specified
Principles of method if other than guideline:
SOP - STR 028
GLP compliance:
no
Type of method:
differential scanning calorimetry
Decomposition:
yes
Decomp. temp.:
335 - 412 °C

Between 110 and 150 °C there is a loss of  imbibition  water/solvent, followed by an exothermic event between 335 - 412 °C (onset = 377.6 °C, enthalpy = 192.4 J/g).

Conclusions:
The test item is a solid which decomposes before melting.
 
Executive summary:

Method

Differential Scanning Calorimetry (DSC) according to the OECD Test Guideline 102.

Results

Between 110 and 150 °C there is a loss of  imbibition  water/solvent, followed by an exothermic event between 335 - 412 °C (onset = 377.6 °C, enthalpy = 192.4 J/g).

Description of key information

Decomposition before melting (334 - 412 °C).

Key value for chemical safety assessment

Additional information

The substance was tested according to the method described into the OECD 102 Guideline.
