Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- Principles of method if other than guideline:
- Melting point was determined by DSC.
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- 175.2 °C
- Decomposition:
- yes
- Decomp. temp.:
- ca. 189 °C
- Conclusions:
- The study was performed according to ASTM D 3418-99 on the substance to be registered itself, the test procedure is well documented and therefore reliability of Klimisch 2 has been assigned. Melting point was determined as 175.2°C, decomposition occurred at ca. 189°C.
- Executive summary:
The melting point of the test substance has been determined to be 175.2°C, decomposition occurred at ca. 189°C, by using differential scanning calorimetry (DSC) in a non-GLP study according to ASTM D 3418 -99.

Description of key information
Differential scanning calorimetry (DSC), similar to OECD 102, according to DIN 51007, ASTM D 3418-99: melting point = 175.2°C, decomposition occurred at ca. 189°C
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 175.2 °C
Additional information
In the available study using differential scanning calorimetry, the melting point was determined to be 175.2°C, decomposition occurred at ca. 189°C. DSC in general is suitable to detect transitions via changes in enthalpy during heating which may be all melting point, boiling point, or decomposition.
Thermogravimetric Analysis however only revealed the start of composition during heating at 162.7 °C. TGA is only able to detect mass changes during heating, e.g. by evaporation of certain compounds during decomposition.
Hence, it can be concluded, despite the differences in onset of decomposition, that the test item melts at 175.2°C, and that the test item definitively decomposes at temperatures close to the melting point without boiling.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
