Additional information
In a static non-GLP study following the procedures of the German Industrial Standard DIN 38412, Part 15 using Leuciscus idus as test species a LC50 (96 h) of greater than 500 mg/L (nominal concentration) was determined (limit test; BASF AG, 1984; report no. 82/42). 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.
The results of a non-GLP study according to Japanese Industrial Standard "JIS K 0102 - 1974 Item 55" with Oryzias latipes as test species support this finding. The fish were exposed under static conditions to two concentrations of the test substance (1000 and 2000 mg/L). No mortality occurred and no symptoms were detectable. The 96-h LC50 was determined to be greater than 2000 mg/L (BASF AG, 1984; report no. 84/216). The test item concentrations were not analytically verified but are assumed to be stable reagrding the substance's properties.
In conclusion, 4-morpholinecarbaldehyde is with high probability acutely not harmful to fish.
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).
