Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

<0.00001 Pa at 25°C

Key value for chemical safety assessment

Additional information

The vapour pressure of test item is expected to be so small that the value is below the measurement range of an experimental determination (e.g. the gas saturation method, 10E-5 Pa) thus the vapour pressure has been calculated.

The calculation was based on Modified Grain Method using recommended MPBPVP module of software EPI Suite v.4.11 with entering the melting point of test item. The calculation yielded a value of 4.59E-16 Pa at 25°C.

This QSPR software complies with the OECD principles which stated in “QSPR prediction of physico-chemical properties for REACH” and was published in the SAR and QSAR in Environment Research in 2013 (Dearden, J.C., Rotureau, P., Fayet G. (2013). QSPR prediction of physico-chemical properties for REACH, SAR and QSAR in Environmental Research, Vol. 24, No.4, 279-318).
