Adequacy of study:
weight of evidence
Study period:
November 18th, 2015
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Qualifier:
according to
Guideline:
other: OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
adopted July 27, 1995
Qualifier:
according to
Guideline:
other: EU Method A.1 (Melting / Freezing Temperature)
GLP compliance:
no
Physical state at 20°C and 1013 hPa:
solid
Form:
not specified
Conclusions:
Solid at 20 °C and 1013 hPa.
Executive summary:

The melting temperature of the test substance was investigated. The Differential Scanning Calorimetry method was used. The procedures used in the study were in accordance with OECD Test Guideline No.102. 

At the temperature of 230 °C an endothermic reaction was recorded, which was probably caused by the water evaporation. A second endothermic peak very low intensity was observed between 340 and 380 °C, caused by the thermal decomposition of the test substance. After the experiment the sample had lost of its mass and the residue had a black colour.

 

Conclusion

Solid at 20 °C and 1013 hPa.
