- Key result
- Decomposition:
- no
- Remarks on result:
- not determinable
- Remarks:
- no endothermic peak was observed below ambient temperature (substance is a liquid at ambient temperture)
- Conclusions:
- No melting/freezing point could be found for the substance
- Executive summary:
In a test investigating the melting/freezing point of the substance using differential scanning calometry, no melting point was observed in the temperature range between -100 °C and 115 °C.
Reference
Results of the DSC-measurementsDuring the cooling phase, no thermal effects were observed,which can be assigned to the freezing of the test item.

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.
