Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 246-278-9 | CAS number: 24468-13-1
Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
The substance rapidly hydrolyses to 2-ethylhexanol, HCl and CO2. The hydrolysis product 2-ethylhexanol is readily biodegradable
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Parent compound 2-ethylhexyl chloroformate (CAS 24468-13-1):
No experimental data are available for the parent compound. However, since the substance is known to hydrolyse rapidly to 2-ethylhexanol (CAS 104-76-7), HCl (CAS 7647-01 0) and CO2 the assessment of the biodegradability is based on the hydrolysis product 2-ethylhexanol. The hydrolysis product 2-ethylhexanol is readily biodegradable according to OECD criteria (see below).
Hydrolysis product 2-ethylhexanol (CAS 104-76-7):
In two ready biodegradability tests according to OECD 301C (Ready Biodegradability; Modified MITI (I); NITE, 2008) and 301F (Ready Biodegradability; Manometric Respirometry Test; BASF AG, 1989) using domestic sewage and sewage of mixed origin (municipal STPs, industrial STPs, lakes, rivers and bays) the O2 consumption was 79% after 14 days (NITE, 2008) and 85.3% after 17 days (BASF AG, 1989).
Conclusion:
Based on the available data, the hydrolysis product 2-ethylhexanol is expected to be readily biodegradable (according to OECD criteria).
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.
