Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:

- Study period:
- From 11 Aug 2020 to 17 Aug 2020
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Version / remarks:
- 2016
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Version / remarks:
- 2006
- Deviations:

- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 0.009 Pa
- Key result
- Temp.:
- 25 °C
- Vapour pressure:
- 0.013 Pa
- Conclusions:
- The vapour pressure of the substance at 20°C and 25°C was determined to be 9.3E-3 Pa and 1.3E-2 Pa, respectively.
- Executive summary:
The vapour pressure of the substance was determined using the isothermal thermogravimetric effusion method in a GLP study based on EC A.4 and OECD 104. Validation of the method was performed using a set of five reference substances.
The vapour pressure regression curve (log PT as function of 1/T; with T in K) of the substance was constructed from weight losses measured at 150°C, 160°C, 170°C and 180°C.
The vapour pressure of the substance at 20°C and 25°C was calculated (extrapolated) from the vapour pressure curve to be 9.3E-3 Pa and 1.3E-2 Pa, resp.

Description of key information
The vapour pressure of the substance was determined using the isothermal thermogravimetric effusion method in a GLP study based on EC A.4 and OECD 104. Validation of the method was performed using a set of five reference substances. The vapour pressure of the substance at 20°C and 25°C was calculated (extrapolated) to be 9.3 x10-3Pa and 1.3 x10-2Pa, respectively.
Key value for chemical safety assessment
- Vapour pressure:
- 0.009 Pa
- at the temperature of:
- 20 °C
Additional information
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.
