Additional information
The key study with CAS 631-41-4 was performed according to EEC Directive, Method C.3. This GLP study was maintained under static conditions with nominal concentrations of 0 (control), 12.5, 25, 50 and 100 mg/L. The test concentrations were analytically confirmed by measurements of GE with UV/VIS detection at the start and at the end of the test duration. The the determined EC50 was > 100 mg/L after 48 hours of exposure.
Based on the available experimental data the substance is concluded to be with high probability acutely not harmful to aquatic invertebrates.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
