- 321.3 °C
- Atm. press.:
- >= 99.3 - <= 99.8 kPa
- Decomposition:
- yes
- Remarks:
- Test item decomposed on melting, in both an air and nitrogen atmosphere
- Conclusions:
- The mean melting temperature of the test substance was determined to be 321.3 °C (594.5 K) at atmospheric pressure, with a relative standard deviation of 0.19% (°C) from the four determinations performed. The test item decomposed on melting, in both an air and nitrogen atmosphere.
- Executive summary:
The study was performed to determine the melting temperature of the test substance using OECD method 102 and EU Method A.1.
The mean melting temperature of the test substance was determined to be 321.3 °C (594.5 K), with a relative standard deviation of 0.19% (°C) from the four determinations performed. The atmospheric pressure was in the range 99.3 to 99.8 kPa. The test substance decomposed on melting, in both an air and nitrogen atmosphere.

Description of key information
The mean melting temperature of the test item was determined according to OECD 102 and EU Method A.1 to be 321.3 °C (594.5 K), with a relative standard deviation of 0.19% (°C) from the four determinations performed. The atmospheric pressure was in the range 99.3 to 99.8 kPa. The test item decomposed on melting, in both an air and nitrogen atmosphere.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 321.3 °C
Additional information
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.
