Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The toxicity to aquatic invertebrates was studied in an acute immobilization test on Daphnia magna accroding to OECD 202. The daphnids were exposed to the test compound over a period of 48 hours in a limit test at the solubility limit (9.3 mg/L). No effects were observed in the test organisms. Thus, the EC50/48h in Daphnia magna is higher than a saturated solution of the test compound. The test was performed according to GLP (report X153, study TX96148).
The toxicity to aquatic plants was studied in an algal growth inhibition test according to OECD 201. Green algae Demodesmus subspicatus were incubated with the test compound over a period over 72 hours at concentrations of 0.07 to 5.31 mg/L. There was a concentration dependent inhibition of growth from concentrations of 0.27 mg/L onwards. The EC50 for the growth rate was 2.4 mg/L, the NOEC was 0.13 mg/L. The test was performed according to GLP (report A09315).
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.
