Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Any other information on results incl. tables

Inorganic compounds were not included in the training data set for the methodology utilised in the estimation program, and are stated to be outside the estimation domain. As the test item is an organometallic compound, with an inorganic entity (copper), the estimated value for the test item has to be treated with caution. It is likely that the estimated vapour pressure is in fact higher than the value which would be yielded experimentally.

Applicant's summary and conclusion

The vapor pressure of copper di(acetate) is estimated to be 0.00239 Pa at 25°C.
