Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 4/11/2000
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Information is derived from a reliable non-GLP in-house study using the transpiration method equivalent to OECD TG 104, gas saturation method.
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- GLP compliance:
- no
- Type of method:
- dynamic method
- Key result
- Temp.:
- 21.5 °C
- Vapour pressure:
- 24 Pa
- Conclusions:
- The vapour pressure of Oxaspirane-819 was investigated using the Transpiration method equivalent to OECD TG 104, gas saturation method, in a reliable non-GLP study. This is a dynamic method and has recently been updated for use of low volatile substances. A precisely known volume of air is sampled through a trap containing the sorbent Tenax TA. The adsorbed compound is desorbed and eluted onto a GC column where it is identified and quantified using a calibration curve. The mass of analyte per unit volume collected is used to calculate the vapour pressure. The vapour pressure of the Oxaspirane-819 was found to be 21.5 Pa at 24°C.
- Executive summary:
The vapour pressure of Oxaspirane-819 was investigated using the Transpiration method equivalent to OECD TG 104, gas saturation method. The vapour pressure of the substance was found to be 21.5Pa at 24°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.
