Description of key information

 The vapour pressure of 2-methylpropane-2-thiol is 19.0 KPa at 20°C.

Key value for chemical safety assessment

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

Additional information

The results are taken from the WHO IPCS International Chemical Safety Card (ICSC 0019, 2004). No information on the primary source of these 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.

This is supported by Zwolinski (1971), which gives a pressure of 20.5 kPa at 21.1°C.
