Description of key information
The acute toxicity to fish was examined in a guideline study (BASF AG, 1991) following German national standard DIN 38412, part L15 (1982) with the species Leuciscus idus. The test fish were exposed to the substance for 96 hours in a static test system. At test termination a LC50 > 10000 mg/L (nominal) was determined.

Additional information
The acute toxicity to fish was examined in a guideline study (BASF AG, 1991) following German national standard DIN 38412, part L15 (1982) with the species Leuciscus idus. The test fish were exposed to the substance for 96 hours in a static test system. The concentration of the test substance was nominal 10000 mg/L. No concentrations of the test substance were measured. At test termination a LC50 > 10000 mg/L (nominal) was determined.
Comparable results were obtained by a supporting study with the close structural analogue CAS 1324-29-4 following OECD guideline 203 with Brachydanio rerio. After the 96 hour exposure period a LC50 > 100 mg/L (nominal) was determined (Ciba-Geigy Ltd. 1989).
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.
