Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydrolysis product 3 -chloropropionic acid: readily biodegradable (according to OECD criteria)
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The parent compound 3 -chloropropionyl chloride (CAS 625-36-5) rapidly hydrolyses in contact with water and forms 3-chloropropionic acid (CAS 107-94-8). The biodegradation potential will, therefore, be assessed based on information available for the hydrolysis product 3-chloropropionic acid (CAS 107-94-8).
3-chloropropionic acid is readily biodegradable in freshwater based on the results of standard ready test that show 95% removal after 28 days (Trénel J. and Kühn R., 1982). Activated sludge was used as inoculum. In an addition, in a Zahn-Wellens test with industrial activated sludge 3-chloropropionic acid was determined to be inherently biodegradable (98% DOC removal after 16 days, BASF AG, 1978)
Based on the available experimental information the hydrolysis product the substance is considered 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.
