Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substance was tested for its acute toxicity to the rainbow trout over a period of 96 hours in a static system. The study was performed according to the OECD Guideline No. 203 and the EEC Directive 92/69 Part C.1.
Based on the results of a range-finding test performed with test article concentrations of 100, 10 and 1.0 mg/l in a static system, a limit test was performed at a test article concentration of 100 mg/l in order to demonstrate that the LC50 is greater than this concentration. Untreated test medium was run in addition to the 100 mg/l test concentration as a control.
The 100 mg/l test concentration and the control were verified analytically by HPLC at the beginning and at the end of the limit test. Measured test article concentrations were 99.4 % of nominal at hour 0 and 97.6 % of nominal after 96 hours of exposure. Consequently, the biological data are expressed as nominal concentrations.
At the 100 mg/l test article concentration, as well as in the control no mortality of fish occurred during the 96-hour exposure period, and no sublethal effects were observed over the 96-hour exposure period. Therefore, the NOEC and LC0 were determined to be ≥ 100 mg/l, and the LOEC, LC50 and LC100 were determined to be >100 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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
