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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

-Description: Dark Green Liquid
-Storage: Room temerature (15 to 30°C) - Key result
- Melting / freezing pt.:
- < -20 °C
- Remarks on result:
- other: Freezing point
- Key result
- Melting / freezing pt.:
- < -60 °C
- Remarks on result:
- other: Melting point
- Conclusions:
- The freezing point of the test substance was <-20°C. No endotherms characteristic of a melting temperature were recorded on either test, therefore the melting temperature is <-60°C. An exothermic reaction followed by an endothermic reaction; 126.06 to 238.05°C (test 1) and 118.16 to 237.33°C (test 2), mean 122 to 238°C. Decomposition was deemed to commence at 122°C. The onset temperatures of the thermograms were 190 and 216°C.
- Executive summary:
The freezing point of the test substance was <-20°C. No endotherms characteristic of a melting temperature were recorded on either test, therefore the melting temperature is <-60°C. An exothermic reaction followed by an endothermic reaction; 126.06 to 238.05°C (test 1) and 118.16 to 237.33°C (test 2), mean 122 to 238°C. Decomposition was deemed to commence at 122°C. The onset temperatures of the thermograms were 190 and 216°C.
