Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- 3-chloropropionyl chloride
- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- Reference substance:
- 3-chloropropionyl chloride
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The assessed substance rapidly hydrolizes and decomposes in water into the main products 3-chloropropionic acid and HCl (CAS 7647-01-0). As HCl will be neutralized under environmentally relevant conditions, its organic hydrolization product 3-chloropropionic acid (CAS 107-94-8) was used for the PBT assessment. The environmental assessment is mainly based on its hydrolysis product 3-chloropropionic acid (CAS 107-94-8).
Since 3-chloropropionic acid is readily biodegradable (according to OECD criteria) it should be regarded as not P/vP. The substance is not B/vB since it has a log Kow less than 3 (see IUCLID chapter 4.7).
Due to the rapid hydrolysis of the parent compound 3-chloropropionyl chloride (CAS 625-36-5) and in absence of the chronic toxicity data for the compound itself, the assessment of T properties is based on the hydrolysis product 3-chloropropionic acid (CAS 107-94-8). 3-chloropropionic acid is not T since the lowest available chronic value is >> 0.01 mg/L (Algae: 72-h ErcC10: 10.1 mg/L, pH-adjusted, analytically verified, ECHA, disseminated data, 2015) and the substance holds no relevant classification.
In conclusion, the parent compound 3-chloropropionyl chloride (CAS 625-36-5) is considered to be neither PBT nor vPvB, based on the available data for the hydrolysis product 3-chloropropionic acid (CAS 107-94-8).
