Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Conclusions:
- The vapour pressure of TRIFLUMURON determined in two heating cycles gave reproducible results. It was not possible to measue the vapor pressure at ambient temperature directly because the pressures were too low. By extrapolating the vapour pressure curve to lower temperatures the following vapour pressures were calculated:
The vapour pressures of TRIFLUMURON are
at 20 °C: 2E-9 hPa
at 25 °C: 4E-9 hPa

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.
