Additional information
To determine the toxicity of 4-morpholinecarbaldehyde to aquatic invertebrates, a non-GLP study according to EEC Directive 79/831/EEC using Daphnia magna as test organism was performed. Based on nominal concentrations the EC50 (48h) was determined to be greater than 500 mg/L (BASF AG, 1987; report no. 1/1679/2 -88 -1679/88). The test item concentrations were not analytically verified but are assumed to be stable regarding the substance's properties: low volatility, high water solubility. not significantly bioaccumulative, adsorption not expected.
It can be concluded that 4-morpholinecarbaldehyde is with high probability acutely not harmful to aquatic invertebrates.
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).
