Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
After evaporation or exposure to the air, the product and its hydrolysis product will be slowly degraded by photochemical processes.
Key value for chemical safety assessment
Additional information
Parent compound: Based on an estimated OH radical rate constant of 10.1126E-12 cm³/(molecule*sec), the half-life of octanoyl chloride was calculated to be 38 h (test conditions: sensitiser for indirect photolysis: OH; 0.5 E06 OH/cm³, 24-h day) (BASF SE, 2009).This estimation refers to dry air. In mist, rain, droplets and aerosols hydrolysis will be the major fate process in air due to the short half-life in aqueous solutions.
Hydrolysis product octanoic acid: Based on an estimated OH radical rate constant of 8.3449E-12 cm³/(molecule*sec), the half-life of octanoic acid was calculated to be 46 h (test conditions: 0.5 E06 OH/cm³, 24 -h day) (BASF SE, 2009).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
