Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The study on acute toxicity of the substance to fish (Danio rerio) was performed under semi-static conditions and the 96 hour-LL50 was determined to be > 100 mg/L (Neuhahn, 2011a).
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 100 mg/L
Additional information
The fish were exposed to a range of concentrations, nominally 25, 50 and 100 mg/L of the substance dissolved in dilution water. Defined loadings of the test item led to a certain percentage proportion of dead fish at the end of the 96 hour study period. Mortalities were recorded at 24 hour intervals. Additionally any abnormal behaviour or appearance of the fish was reported every 24 hours.
After 96 hours of exposure a LL 50 of >100 mg/L (nominal) was determined.
The results are expressed in terms of Lethal Loading (LL). As the test item is a UVCB substance and no information about the correlation between molecular weight und the structural formula of the test item are available, Water Accommodated Fraction (WAF) were used to test effects at different effective loadings and no specific analysis was performed. With the sponsor's agreement, the content of the test item during the exposure period was verified by DOC determination.
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.
