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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Regression calculation
- A graph was plotted of Log₁₀(vapour pressure in hPa) (y axis) against 1/(temperature in K) (x axis).
- For a copy of this graph please see attached illustration.
- The calculated regression line was: y = -2139.5x + 7.534
- The coefficient of determination (R²) of this line was 0.9999
Description of key information
The vapour pressure of nonanal was determined to be 2 hPa at 20 °C in a study to DIN EN 13016-2 by extrapolating from recorded vapour pressures at higher temperatures.
Key value for chemical safety assessment
- Vapour pressure:
- 2 hPa
- at the temperature of:
- 20 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
