Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
The fish-acute toxicity study was conducted to Cyprinus carpio, according to the OECD Guideline 203 (1984). Fish were exposedfor 96 h in a static system to a nominal concentration range from 56 to 1000 mg/l and a control.
Analytical analysis carried out during the range finding study revealed the stability of test substance during 96 h.Moreover, the actual concentration was more than > 95 % the nominal concentration in all samples taken during the test period.
Based on these data the LC50 after 96 hours of exposure was calculated to be 748 mg/l, without mortality at 560 mg/l and 100 % mortality at 1000 mg/l.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
