Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The Henry's Law constant for octane-1-thiol has been calculated to be 442 Pa-m3/mol.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
442
at the temperature of:
20 °C

Additional information

This equation for calculating the Henry's Law Constant is indicated in the Guidance on information requirements and chemical safety assessment (IR & CSA) Chapter 16 "Environmental exposure estimate" (Equation R.16-10) and is therefore considered an appropriate technique. There are limitations design and reporting, but the calculated value is considered suitable for use for this endpoint.

This result indicates that octane-1 -thiol is expected to volatilise rapidly from the aquatic environment.
