Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 vapour pressure of the test material has been determined to be 0.513 Pa at 25 °C.
Key value for chemical safety assessment
- Vapour pressure:
- 0.051 Pa
- at the temperature of:
- 25 °C
Additional information
The vapour pressure of the test material was investigated in accordance with the standardised guidelines OECD 104 and EU Method A.4 under GLP conditions.
The method selected for the determination was the vapour pressure balance method. A preliminary run was undertaken over the temperature range 20 to 124 °C to provide information for a suitable temperature range for the determination. A sequence of runs was started after a sample of the test material had been under vacuum for approximately 44.25 hours.
The final 5 of 10 runs were deemed to have taken place after the test system had reached equilibrium with regard to the vapour pressure and the result of these were therefore used to determine the definitive vapour pressure of the test material.
Under the conditions of this study, the test material was found to have a vapour pressure of 0.0513 Pa at 25 °C.
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.
