Description of key information

The vapour pressure of ethanethiol is 58.9 KPa at 20˚C.

Key value for chemical safety assessment

Vapour pressure:
58.9 kPa
at the temperature of:
20 °C

Additional information

The key result, with a reported vapour pressure of 58.9 kPa at 20 °C, is taken from the WHO IPCS International Chemical Safety Card (ICSC 0470, 2004). No information on the primary source of this data or the methods used is available. However, this information is taken from an internationally peer-reviewed chemical safety card and can be considered reliable and suitable for use as the key study for this endpoint. The key study is supported by Zwolinski (1971), which gives a vapour pressure of 60.5 kPa at 21 °C.
