Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1989
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- GLP compliance:
- yes
- Type of method:
- static method
- Key result
- Test no.:
- #1
- Temp.:
- ca. 25 °C
- Vapour pressure:
- ca. 7 Pa
- Conclusions:
- The vapour pressure of O-Methylisourea sulphate is 7.4 Pa at 25°C
- Executive summary:
The vapour pressure of O-Methylisourea sullphate was determined to be 7.4 +/- 0.7 Pa at 25°C, using the static technique.
In case the last measurements were extrapolated to 25°C, an estimation for the upper limit of the vapour pressure of the pure compound could be made. The upper limit of the vapour pressure for the pure compound i.e. O-Methylisourea sulphate was estimated to be 0.3 +/- 0.1 Pa at 25°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.
