Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification
The only study available is an acute fish study according to EU method C.1.
Taking into account the determined effect values after 96h, based on nominal concentrations, i.e. LC50, LC0, EC50, EC0 = resp. >= 1 mg/L, based on mortality resp. swimming behaviour, the substance does not need to be classified as aquatic acute cat. 1 according to Regulation (EC) No. 1272/2008. Since 1 mg/L (nominal) was the only concentration tested, a classification as aquatic chronic cat. 2 or lower can not be categorically excluded. However, this concentration resulted in precipitation, i.e. it is above the water solubility of the substance. Based on the procedure as described in the test report, the test solutions need to be considered as a WAF. Hence, it can be assumed that the observed effects, i.e. actually the lacking of mortality or behavioural abnormalities, was observed at concentrations maximally as high as the substance water solubility and the actual LC50 would virtually be above the water solubility of the substance. In this case, referring to the actual concentration, the safety net classification as aquatic chronic cat. 4 would be triggered.
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.
