Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Three studies on the acute toxicity to fish using three different specis are available. Hence, a weight of evidence approach was applied.
An acute non-GLP flow-through test by Brooke et al. (1984) on Pimephales promelas showed a LC50 (96h) of 18.8 mg/L, related to the nominal concentration.
Two non-GLP non-guideline tests by Hoechst AG (1979) using Lepomis gibbosus and Salmo gairdnerii (new name: Oncorhynchus mykiss) revealed LC50 after 96 hours of exposure of 37.3 mg/L and 42.0 mg/L, respectively, related to the nominal concentration. In a WoE approach results ranges fom 18.8 mg/L to 42.0 mg/L, with lowest value of 18.8 mg/L. Hence, the substance is considered acutely harmful for fish.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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
