Additional information

The toxicity of 2-ethylhexyl cyanoacetate (CAS 13361-34-7) to algae was tested according to EU Method C.3 (Algal Inhibition test). The test was performed with Desmodesmus supsicatus under static conditions. Based on measured test concentrations, the 72-h ErCC50 was determined to be 4.5 mg/L (72-h Er10: 1.91 mg/L).
