Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

vapour pressure
Type of information:
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model, but not (completely) falling into its applicability domain, with adequate and reliable documentation / justification
The scientific validity of the (Q)SAR model has been established in accordance with the OECD Principles for (Q)SAR Model Validation.
Justification for type of information:
QSAR prediction
Principles of method if other than guideline:
QMRF and QPRF are attached in IUCLID
GLP compliance:
not specified
Type of method:
other: QSAR
25 °C
Vapour pressure:
0 Pa
Remarks on result:
other: = 3.68E-07 mm Hg (Modified Grain Method)

Supporting documentation is provided in the attached QPRF and QMRF.

The vapour pressure of the test substance was estimated to equal 0.000049 Pa.
Executive summary:

A vapour pressure of 3.68E-07 mmHg (Modified Grain Method) was estimated for the test substance using the estimated boiling point of 328.07°C and measured melting point of 142.4°C. This equates to a VP of 4.9E-05 Pa.
