Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of information:
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
accepted calculation method
Justification for type of information:
For the calculation EPI Suite (MPBPVP v1.43) was used.
This is an accepted calculation method and EPI Suite is generally recommended by the Guidance documents.
no guideline required
Principles of method if other than guideline:
For a calculation method a test guideline is generally not required.
GLP compliance:
GLP compliance is only relevant for experimental studies and thus not applicable.

The vapour pressure calculated with EPI Suite was determined to be 1.03E-10 Pa at 25 °C.
Executive summary:

EPI Suite and the implemented calculation method (MPBPVP v1.43) are accepted methods for the determination of physical-chemical properties by QSAR.

A very low vapour pressure for the test substance is reasonable as it is a solid substance that does not melt or sublime up to ca. 200 °C.

The registrant is aware of remeining uncertainties caused by the methods used for calculation.

Nevertheless an experimental study is not justified because of the very low vapour pressure. The relevant guideline (OECD 104) describes different methods with their recommended ranges. The lowest detectable limit is stated with 1E-10. Thus the vapour pressure of the test substance can be considered to be around or even below the limit that can be detected with recommended experimental methods.
