- Atm. press.:
- 1 013.3 hPa
- Decomposition:
- yes
- Decomp. temp.:
- 170 °C
- Remarks on result:
- not determinable
- Conclusions:
- Under the conditions of the study, the DSC-measurements in closed glass crucibles showed no endothermic effect until the decomposition of the test substance beginning at 170°C. The test substance has no melting point at atmospheric pressure.
- Executive summary:
A study was conducted to determine the melting point of the test substance according to OECD Guideline 102 and EU Method A.1, in compliance with GLP.
The test was carried out with the purified test substance. The determination of the melting point/melting range was carried out by differential scanning calorimetry (DSC: Mettler-Toledo TA8000).
Under the conditions of the study, the DSC-measurements in closed glass crucibles showed no endothermic effect until the decomposition of the test substance beginning at 170°C. The test substance has no melting point at atmospheric pressure.
Reference
The differential scanning calorimetry (DSC) measurements in closed glass crucibles showed no endothermic effect until the decomposition of the test substance beginning at 170°C. The test substance has no melting point at atmospheric pressure.
Description of key information
The test substance has no melting point at atmospheric pressure (Smeykal, 2006).
Key value for chemical safety assessment
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.
