Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
The acute aquatic toxicity has been tested for Reactive Red 239.
The 96 h LC50obtained in static studies on zebra fish (Brachydanio rerio) > 500 mg/L and the 96 hour NOEC was 500 mg/l. The 24 h EC50in a static Daphnia magna immobilisation test was 37.2 mg/L (extrapolated value). However, the structural analogue SA01 assessed in a semi-static Daphnia magna immobilisation test system over an exposure period of 48 hours had no toxic effect on daphnids at up to at least 160 mg/L. In addition, in the 21-day semi-static test in Daphnia magna a NOEC of 30 mg/L was determined for immobility and the NOEC for reproduction was above or equal to 30 mg/L. The validity of the result of the acute toxicity study in Daphnia magna is therefore questionale.
The 72 -hour toxicity in green algae (sacenedesmus subspicatus) showed a NOEC of > 320 mg/l.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
