Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
5-Chlorovaleryl chloride is expected to rapidly hydrolyse in contact with water to form 5-chlorovaleric acid (CAS 1119-46-6) and hydrogen chloride (CAS 7647-01-0). No further hydrolysis of 5-chlorovaleric acid is to be expected as it does not contain hydrolysable functional groups.
Key value for chemical safety assessment
Additional information
No experimental data on the hydrolysis of 5 -chlorovaleryl chloride is available. For the acid chlorides category, hydrolysis is the primary reaction in aqueous systems and has been shown to occur very quickly with half-lives of ≤ 30 min (OECD SIDS, 2008). All category members hydrolyze in the presence of water or moisture to form hydrochloric acid (CAS 7647 -01 -0) and the corresponding organic acid. In the case of 5 -chlorovaleryl chloride the corrsponding organic acid is 5 -chlorovaleric acid (CAS 1119 -46 -6) which at its turn is considered to be hydrolytically stable as it does not contain hydrolysable functional groups.
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.
