Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Several studies exist for this end point at different temperatures: at 20 °C, the vapor pressure is 17.3 hPa.
Key value for chemical safety assessment
- Vapour pressure:
- 17.3 hPa
- at the temperature of:
- 20 °C
Additional information
Different studies have been performed for the determination of the vapor pressure of 2 -nitropropane; all are of good quality, made on a pure substance. The Antoine equation has been determined and gives a good prediction of the vapour pressure of 2-nitropropane at different temperatures: logPmmHg = 7.081995 - 1422.122/(t + 218.258) with PmmHg = vapour pressure expressed in mm Mercury and t = temperature in °C.
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.
