Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Negligible.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
Additional information
According to the REACH Regulation (EC 1907/2006) Annex VII Column 2: the study does not need to be conducted if the melting point is above 300 °C. If the melting point is between 200 °C and 300 °C, a limit value based on measurement or a recognised calculation method is sufficient.
The melting point of test item is between 206 and 236 °C, followed by degradation; therefore an estimated value of vapour pressure has been calculated by EPI Suite 4.1.
The value of vapour pressure has been calculated by EPIsuite 4.1:
Vp = 0.0000000372 Pa at 25 °C
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
