Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
Conclusion on classification
Classification and labelling has been based upon the key information for the ecotoxicity endpoints. The results of these studies are as follows:
96 hour LC50 (fish): 0.058 (Skelley, 1989)
64 day NOEC (fish): 14.5 and 48.5 µg/L (Call et al, 1984)
48 hour EC50 (Daphnia): 0.24 mg/l (Gersich, F.M. and M.A. Mayes, 1986)
72 hour ErC50 (algae): 0.74 mg/l (Kamath, 2006)
It should also be considered that the substance does not meet the definition of a readily biodegradable substance (Indrani, 2006).
The lowest of these results is the 96 hour LC50 for fish (Skelley, 1989), and this end-point has been used for classification and labelling and this meets the criteria under 67/548/EEC and EC Regulation 1272/2008 as follows:
67/548/EEC:
R50 and R53: Very toxic to aquatic organisms and May cause long-term adverse effects to the aquatic environment.
EC Regulation 1272/2008:
Hazardous to the aquatic environment, Acute: Category 1 and Chronic: Category 1
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.
