Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Stability
Parent compound 3-chloropropionyl chloride(CAS 625-36-5): In contact with water, the substance is expected to rapidly hydrolyse. This estimation refers to dry air. In mist, rain, droplets and aerosols, hydrolysis will be the major fate process of the chloroformate due to the short half-life in aqueous solution. Therefore, this estimate may be of low relevance.
Hydrolysis product 3-chloropropionic acid (CAS 107-94-8): According to structural properties, hydrolysis is not probable. In addition, the substance is readily biodegradable according to OECD criteria.
Phototransformation in air:
After evaporation or exposure to air, the substance and its hydrolysis product will be slowly degraded by photochemical processes.
Biodegradation
3 -chloropropionyl chloride (CAS 625-36-5) is rapidly hydrolysed in contact with water and forms 3-chloropropionic acid (CAS 107-94-8) and HCl. The hydrolysis product 3-chloropropionic acid is readily biodegradable (Trénel J. and Kühn R., 1982). Regarding the hydrolysis products HCl, biodegradation is not applicable due to the inorganic character of this molecule.
Bioaccumulation
Due to the low log Kow of the parent compound and its hydrolysis products, significant accumulation in organisms is not to be expected (calculated, BASF SE, 2019).
Transport and distribution
Parent compound 3 -chloropropionyl chloride (CAS 625-36-5): Adsorption to the solid soil phase is not expected.
Hydrolysis product 3-chloropropionic acid (CAS 107-94-8): Adsorption to the solid soil phase is not expected.
Henry's Law Constant
Parent compound methyl 3 -chloropropionyl chloride (CAS 625-36-5): From the water surface the substance will slowly evaporate into the atmosphere. However, 3-chloropropionyl chloride hydrolyses rapidly in contact with water to form 3-chloropropionic acid (CAS 107-94-8). Therefore, this model calculation may be of low relevance.
3-chloropropionic acid (CAS 107-94-8) From the water surface the substance will not evaporate into the atmosphere.
Distribution modeling
Parent compound 3 -chloropropionyl chloride (CAS 625 -36 -5): Over time, the substance will preferentially distribute into the compartment water (74.1%) and slightly into the compartment air (25.9%).
Hydrolysis product 3 -chloropropionic acid (CAS 107 -94 -8): Over time, the substance will preferentially distribute into the compartment water (92.7 %) and slightly into the compartment air (7.23 %).
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).
