Reference
Description of key information
One OECD 203 GLP study is available. The EC50 is greater than the maximum water solubility, thus it is not acutely toxic to fish.
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
