Description of key information

The Henry's Law constant for dimethyl sulphide has been calculated to be 446.3 Pa-m3/mol.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
446.3
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 would indicate that dimethyl sulphide is expected to volatilise significantly from the aquatic environment.
