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.

Additional information

The analogue substance was tested for acute immobilisation with Daphnia Magna following OECD 202 in two different studies. The more recent study showing a more conservative result of the toxicity was chosen as key study (Clariant, 2013). The test item under static conditions over 48h showed an EC50 equal to 30.2 mg/l (calculated based on the effects on the nominal concentrations).

Based on the read across considerations the results of acute immobilisation with Daphnia Magna can be applied to the target substance with EC50, 48h equal to 30.2 mg/l.
