Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Remarks:
EpiSuite
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
Justification for type of information:
The substance falls within the applicability domain of the selected (Q)SAR method.
Qualifier:
according to guideline
Guideline:
other: EPI SUITE v 4.11
GLP compliance:
no
Type of method:
other: calculation
Key result
Temp.:
25 °C
Vapour pressure:
ca. 1.37 mm Hg
Conclusions:
Under the study conditions, the vapour pressure of the test substance was established at 1.37 mm Hg at 25°C.
Executive summary:

The vapour pressure of the test substa,ce was deterlined by modelling using EPI SUITE v 4.11. The derived value was the mean of the vapour pressures calulated by the Antonie and Grain methods. Under the study conditions, the vapour pressure of the test substance was established at 1.37 mm Hg (182.65 Pa) at 25°C (US EPA, 2017).
