Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 vapor pressure of bromacil at 25°C was determined to be 3.1 x 10^-7 mm Hg (4.1 x 10^-5 pascals), using the gas saturation method at five temperatures from 122-160°C. The value of the vapor pressure at 25°C was obtained by extrapolation of the high temperature data.
