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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- 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 limited documentation / justification
- Remarks:
- Estimated by calculation using EPI Suite (v. 4.0) Quantitative Structure Activity Relationship (QSAR) computer model. EPI Suite has undergone detailed review by a panel of EPA’s independent Science Advisory Board (SAB) (http://www.epa.gov/sab/).
- Justification for type of information:
- EPI Suite has undergone detailed review by a panel of EPA’s independent Science Advisory Board (SAB) (http://www.epa.gov/sab/).

Materials and methods
Test guideline
- Guideline:
- other:
- Principles of method if other than guideline:
- General model to estimate the vapor pressure (VP) of organic compounds. VP is estimated by three methods; all three methods use the normal BP. The first is the Antoine method (see chapter 14 of the "Handbook of Chemical Property Estimation Methods" by W.J. Lyman et al., Washington, DC: American Chemical Society, 1990). The second is the modified Grain method, and the third is the Mackay method (see Neely & Blau reference above). The MPBPVP program will then select or calculate a preferred (suggested) VP (e.g., the Grain method is recommended for solids).
- GLP compliance:
