Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
There is only one acute toxicity study towards fish available with some deficiencies, as the substance is actually highly insoluble in water and testing resp. analytical determinations of the actual test item concentrations is technically not feasible. According to Regulation 1272/2008, ‘Safety net’ classification, Category Chronic 4, is adequate in cases when data do not allow classification under the above criteria but there are nevertheless some grounds for concern. This includes, for example, poorly soluble substances for which no acute toxicity is recorded at levels up to the water solubility (note 4), and which are not rapidly degradable in accordance with section 4.1.2.9.5 and have an experimentally determined BCF≥500 (or, if absent, a log K ow≥4). Even though toxic effects occurred, the nominal or therein measured effect values are higher (or unknown) than the recently determined water solubility of the substance, so classification as Chronic 4 is considered adequate.
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.
