Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 air, the substance and its hydrolysis product 2-ethylhexanol will be slowly degraded by photochemical processes.
In contact with water, 2-ethylhexyl chloroformate will hydrolyse rapidly.
Additional information
Phototransformation in air:
In air, 2-ethylhexyl chloroformate is expected to be photodegraded by OH-radicals with a half-life of 1.5 d (EPISuite, AOPWIN v1.92, BASF SE, 2021). 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 2-ethylhexanol (CAS 104-76-7): A half-life of 1.2 d was calculated for the degradation in the atmosphere by OH-radicals (EPISuite, AOPWIN v1.92, BASF SE, 2021).
Hydrolysis:
The parent compound 2-ethylhexyl chloroformate hydrolyses fast (DT50 = 30.2 min at pH 7 and 25°C, OECD TG 111; SafePharm, 2003) and decomposes to 2-ethylhexanol (CAS 104-76-7) and HCl (CAS 7647-01-0).
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.
