Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Based on the reliable data, after 48 hours of exposure to the test substance, an EC50 = 535.89 mg/L was calculated for Daphnia magna.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 535.89 mg/L
Additional information
Only two short term acute toxicity tests on aquatic Invertebrates was available de Nadai (2009) and Pallas and Dion (1983). Too few information were available in the last study. On the opposite, de Nadai (2009) was extensively detailed. The study design used sealed test vessels adapted to volatile substance as for other nitrile substances yet the test substance is not volatile. However this design had no impact on the results presented. The results are deemed to be fully reliable with the exceptions that no chemical analysis were performed. At the end of the test it was calculated a 48h-EC50 = 535.89 mg/L.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
