Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Executive summary:
Method
The test item melting point was determined using the Differential Scanning Calorimetry (DSC) according to the OECD Guidelines 102 and 103.
Results
Water/imbibition solvent release was observed between 83 °C and 120 °C, followed by a little endothermic event between 188 °C and 294 °C (onset at 205.7 °C, enthalpy: -23.2 J/g) and then decomposition between 353 °C and 416 °C (onset at 356.8 °C, enthalpy: 42.7 J/g); therefore boiling point is not recorded.
At 20 °C and 1013 hPa, the substance is solid.

- Type of information:
- other: qualitative assessment
- Adequacy of study:
- weight of evidence
- Study period:
- 2016
- 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:
- The evaluation of physical state and appearance was based on a qualitative assessment and analytical characterization.
- GLP compliance:
- no
- Physical state at 20°C and 1013 hPa:
- solid
- Form:
- solid
- Colour:
- Orange
- Substance type:
- other: Metal complex
- Conclusions:
- At 20 °C and 1013 hPa, the substance is a orange powder.
- 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 orange powder at 101325 hPa and 20 °C.
