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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key experimental value of vapour pressure at 20°C: 30 Pa +/- 2 Pa
Supporting experimental value of vapour pressure at 20°C: 88.4 +/- 3.3 Pa
Key value for chemical safety assessment
- Vapour pressure:
- 30 Pa
- at the temperature of:
- 20 °C
Additional information
The vapour pressure was determined in two studies using the same method: the static method.
These determinations have been performed according recognized international guidelines and under GLP. No deviations from the guidelines was observed in these studies.
In the supporting study, the sample has not been outgassed in the apparatus at low temperature before the measurement of the vapour pressure. The outgassing have been performed in the key study. This difference can explained the gap between the key value and the supporting value. Indeed, some volatile impurities have probably affected the value of vapour pressure determined in the supporting study.
As recommended in the ECHA Guidance document R 7.A, the vapour pressure obtained with the lowest influence of volatile impurities of the test substance was chosen as the key value.
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.
