Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Administrative data
Link to relevant study record(s)
- 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
- Justification for type of information:
- According to the REACH Regulation (EC 1907/2006), Annex VII, Column 2, if the melting point is between 200°C and 300°C, a limit value of vapour pressure based on measurement or a recognised calculation method is sufficient.
- Principles of method if other than guideline:
- Estimate by MPBPWIN as implemented in EPI Suite v4.11.
- Temp.:
- 25 °C
- Vapour pressure:
- 0 Pa
- Conclusions:
- Estimated vapour pressure is 3.72E-8 Pa at 25 °C (modified Grain method).
- Executive summary:

Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa

- 25 °C
Additional information
Based on the REACH Regulation, Annex VII, Column 2, if the melting point is between 200 and 300 °C, a limit value of vapour pressure based on measurement or a recognised calculation method is sufficient.
According to the OECD Guideline 104 the vapour pressure of liquids and solids can be estimated by use of the modified Watson correlation, the only experimental data required is the normal boiling point. The method is applicable over the pressure range from 105 Pa to 10-5 Pa. Nevertheless for the Substance no boiling point was detected up to 440 °C, therefore the vapour pressure was predicted by MPBPWIN as implemented in EPI Suite v4.11, by using smile notation of the substance as input.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
