Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
vapour pressure
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Qualifier:
no guideline followed
Principles of method if other than guideline:
Modeled data (OPERA)
GLP compliance:
no
Vapour pressure:
6.12 Pa
Remarks on result:
other: Modeled data (OPERA); 4.59e-9 mm Hg
Conclusions:
Modeled data indicates that the test substance has a vapor pressure of 4.59e-9 mm Hg (inside domain with associated QMRF).
Executive summary:

The OPERA model was used to predict the vapor pressure of the test substance. The model indicates that the test substance has a vapor pressure of 4.59e-9 mm Hg (inside domain with associated QMRF). Additional supporting documentation is provided in the prediction report attached in IUCLID.
