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.
