Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Henry's Law Constant (25°C) = 79.3 Pa m3/mol 

Key value for chemical safety assessment

Additional information

The Henry's Law Constant of methyl octanoate (CAS No. 111-11-5) was experimentally determined, being 7.83 x 10E-04 atm m3/mol at 25 °C (equivalent to 79.3 Pa m3/mol)(Buttery et al., 1969). This value indicates that, once released into the environment, the substance has potential for partial evaporation from water surfaces into air.
