Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
July 27th, 2015
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Test conducted according to internationally accepted testing guidelines.
Reference:
Composition 0
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Principles of method if other than guideline:
The test was performed according to the SOP - SRT 028 protocol.
GLP compliance:
no
Type of method:
differential scanning calorimetry
Test material information:
Composition 1
Decomposition:
yes
Decomp. temp.:
261 - 293 °C

The imbibition water/solvent release was observed between 50 -145 °C (onset at 59.8 °C, enthalpy: -16.2 J/g), followed by decomposition between 261 - 293 °C (onset at 264.3 °C, enthalpy 21.1 J/g).

Conclusions:
The substance decomposes before melting (261 - 293 °C)
Executive summary:
The test item melting point was determined using the Differential Scanning Calorimetry (DSC) according to Directive EC 440/2008 Method A.1., OECD Test Guideline 102 (1995).

The imbibition water/solvent release was observed between 50 -145 °C (onset at 59.8 °C, enthalpy: -16.2 J/g), followed by decomposition between 261 - 293 °C (onset at 264.3 °C, enthalpy 21.1 J/g).

Conclusion

The substance decomposes before melting (261 - 293 °C)

Description of key information

The substance decomposes before melting (261 - 293 °C)

Key value for chemical safety assessment
