Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusions:
Both, the target and the source substance have very low water solubility. Based on the very close chemical similarity of both substances the high toxicity to Daphnia observed in the short-term study with the source substance very likely also applies to the target substance. The EC50 value of 0.37 mg/l will be used in the CSR and for classification.
