Description of key information

 IC50 (0.5h) > 100 mg/L and NOEC (0.5h) > 100 mg/L [OECD TG 209; test item: structural analogue with EC 413-750-2]

Key value for chemical safety assessment

Additional information

The acute toxicity of the structural analogue to microorganisms has been determined in a test according to OECD-Guideline 209. The IC50 (0.5h) and the NOEC (0.5h) value were > 100 mg/L. These results show that at a concentration in excess of the water solubility level of the test material, the test material does not have an effect on the respiration rate of activated sewage sludge.

Since EC 700-397-7 is a near analogue to the test substance (EC 413-750-2), the experimental data from this substance were used in a read-across approach.
