Additional information
The analogue substance was tested following OECD 203 up to a nominal concentration of 100 mg/l (actual 78 mg/l, after a preliminary screening). No mortalities of the test fish was observed while no effects could be observed due to the strong coloration of the test medium.Under the experimental conditions the LC50, LC0 is equal to 100 mg/l (nominal).
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.
