Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A weight of evidence approach was used to address this endpoint.
Anon. (MSDS) (2009): The vapour pressure at 25 ºC was 143 mmHg (19.065 kPa).
USA EPA (2010): The computer simulated prediction at 25 ºC is 137 mmHg (18.265 kPa).
Boublík. T, et. al. (1984): The experimentally determined vapour pressure at 20 ºC is 110.8 mmHg (14.772 kPa).
Key value for chemical safety assessment
- Vapour pressure:
- 14.772 kPa
- at the temperature of:
- 20 °C
Additional information
From the available sources, the vapour pressure of 1-bromopropane was determined to be between 137 - 143 mmHg at 25 ºC. As expected, the value at 20 ºC was lower at 110.8 mmHg. As the value at 20 °C was obtained from an experimental result-based peer reviewed literature source, this is selected as the key value.
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.
