Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Hazard for air
Hazard for terrestrial organisms
Soil
- Hazard assessment conclusion:
- no exposure of soil expected
Hazard for predators
Secondary poisoning
- Hazard assessment conclusion:
- insufficient hazard data available (further information necessary)
Additional information
For this level of supply and anticipated exposure to the environment, only the freshwater PNEC can be evaluated.
Only limited data has been provided by ECHA, but it is apparent that the substance was poorly stable under the conditions of the study, despite using semi-static method for renewal of test media. It is known that the substance is very unstable in light and it can be assumed that the toxicity was as a result of exposure to one or more of the abiotic metabolites.
Conclusion on classification
Concluded to be R53 based on aquatic toxicity and lack of significant biodegradation.
CLP classification Aquatic Chronic 4, H410
