- appearance / physical state / colour
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Study period:
- November 04th, 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- adopted July 27, 1995
- Principles of method if other than guideline:
- The thermal behaviour of the test substance was investigated by the Differential Scanning Calorimetry assay.
- GLP compliance:
- no
- Physical state at 20°C and 1013 hPa:
- solid
- Conclusions:
- The substance is a solid at 20 °C and 1013 hPa.
- Executive summary:
The thermal behaviour of the test substance was investigated by the Differential Scanning Calorimetry assay. The procedures used in the study were in accordance with OECD Test Guideline No. 102.
During the first experiment, a first endothermic peak was observed between start temperature and 180 °C, probably caused by the water evaporation. The second endothermic peak was observed between 235 and 356 °C, caused by the thermal decomposition of the test substance. After the experiment the sample had lost 1.19 mg (44.07 %) of its mass and the residue had a black colour.
The second experiment confirmed that the peak at 180 °C was caused by the water evaporation: after the experiment the sample had lost 0.22 mg (7.36 %) of its mass and the aspect was not change.
Conclusion
The substance is a solid at 20 °C and 1013 hPa.

- Type of information:
- other: semi-qualitative assessment
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: all evaluations are based on information about specification (technical standard), experience in dealing with the substance and visual evaluation
- Principles of method if other than guideline:
- All evaluations are based on information about specification (technical standard), experience in dealing with the substance and visual evaluation.
- GLP compliance:
- no
- Physical state at 20°C and 1013 hPa:
- solid
- Key result
- Form:
- powder
- Colour:
- Dark blue/purple
- Substance type:
- organic
- Conclusions:
- Dark blue/purple organic powder at 20 °C and 1013 hPa.
- Executive summary:
All evaluations are based on information about specification (technical standard), experience in dealing with the substance and visual evaluation.
The substance is a dark blue/purple organic powder at 20 °C and 1013 hPa.
