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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 of key information
End point waived as testing scientifically not feasible. Substance would have a very low vapour pressure which is confirmed by EPISuite calculated value (2.15 x 10-14 mmHg) which is less
than minimum permitted value. As such 1 x 10-6 Pa used for CSA purposes only
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
Additional information
The sample did not exhibit a boiling point as the temperature of the event at approximately 310°C was unchanged from atmospheric pressure to 100 mbar (< 1°C). This is clearly a decomposition event and therefore a vapour pressure due to the sample cannot be determined. The end point is thus waived on the basis of testing being scientifically not feasible
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.
