Description of key information
4-[(2-chloroethyl)(ethyl)amino]benzaldehyde is acutely very toxic for aquatic invertebrates.
Key value for chemical safety assessment
Additional information
Two guideline studies on the toxicity of benzaldehyde, 4-[(2-chloroethyl)(ethyl)amino]benzaldehyde on daphnids are available.The results indicate a very high acute toxicity of the test substance on water fleas.
The acute toxicity of 4-[(2-chloroethyl)(ethyl)amino]benzaldehyde to the water flea Daphnia magna was determined according to Directive 79/831/EEC, C.2. The test was performed under static conditions for 48 hours testing the immobility of daphnids at a nominal concentration range between 0.078 and 10 mg/L. The test of 4-[(2-chloroethyl)(ethyl)amino]benzaldehyde to the freshwater crustacean Daphnia magna resulted in an EC50 value (48 h) of 0.82 mg/L.
A second test was performed according to OECD guideline 202 at nominal concentrations of 0, 0.05, 0.10, 0.22, 0.50, 1.0 and 2.2 mg/L of the test substance.The testing of the acute toxicity of 4-[(2-chloroethyl)(ethyl)amino]benzaldehyde to the freshwater crustacean Daphnia magna resulted in an EC50 value (48 h) of 0.58 mg/L under static conditions.
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).
