Description of key information

The Henry's Law Constant for ethanethiol has been calculated to be 544 Pa.m3/mol at 25°C.

Key value for chemical safety assessment

Additional information

The equation for calculating the Henry's Law Constant is indicated in REACH Technical Guidance Chapter R.16 (ECHA, 2012) (Equation R.16-10) and is therefore considered an appropriate technique.

The calculated Henry’s Law Constant at 25°C is 544 Pa.m3/mol

This result indicates that ethanethiol has the potential to volatilise rapidly from surface water.
