Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The maximum vapour pressure of the test substance at 25°C was estimated to be 1.0E-05 Pa using the vapour pressure balance method (GLP-compliant study in accordance with EC A.4). The result was based on only one run because of degassing/condensation issues during the measurements. Also the result was outside the recommended range of 1E-03 to 1 Pa for the vapour pressure balance method. The value of 1.0E-05 Pa should therefore be regarded as an indicative value.
The vapour pressure of the substance was calculated to be 6.4E-05 Pa at 25°C using the modified Watson correlation method. As the substance has no boiling temperature, this temperature (625 K) was calculated from the structural formula. The vapour pressure result for the substance should therefore be considered as a value with a great uncertainty.
Conclusion: the calculated vapour pressure confirmed the estimated result from the vapour pressure balance method.

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.
