Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 4-nitrobenzenesulfonylchloride
- Type of composition:
- legal entity composition of the substance
- State / form:
- solid: particulate/powder
- Related composition:
- 4-nitrobenzenesulfonylchloride
- Reference substance:
- 4-nitrobenzenesulfonylchloride
- PBT status:
- the substance is not PBT / vPvB
- Justification:
An evaluation of the inherent properties of 4 -nitrobenzene-1 -sulfonyl chloride is performed against the ANNEX XIII criteria. If insufficient data were available, the screening criteria as laid down in ECHA Guidance on information requirements and chemical safety assessment Chapter R.11: PBT Assessment (2008) were applied.
In a guideline study on readily biodegradability following the OECD 301B (Timmer, 2017), no significant biodegradation was observed for the substance. As the substance is concluded not to be readily biodegradable and appears to be hydrolytically stable, it should be considered potentially P and vP.
The available evidence on the bioaccumulation potential for the substance indicates that the screening criteria for bioaccumulation potential (B and vB) are not met. Based on a log Kow values for 3 degradation products, a low BCF can be estimated. Since the log Kow of the degradation products are < 4.5, the screening criteria for bioaccumulation are not fulfilled and the substance is concluded not to have a bioaccumulative potential (not B / not vB).
The substance is classified as Muta2 and Repro 2 fulfilling the T properties.
As a conclusion, taking into account the conclusions that the substance is P and vP, but not B/vB, T, the substance should not be considered as a PBT/vPvB substance.
