Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In the absence of ecotoxicity data for this substance data has been read across from a soluble rhenium compound, as is standard practice for the hazard and risk assessment of metals. The results of ecotoxicity testing with sodium rhenate have been read across and expressed as perrhenic acid in order to provide an indication of the toxicity of perrhenic acid. The EC50 values expressed as perrhenic acid are >91.95 mg/L and 209.44 mg/L. As the lowest EC50 is a greater than value it is not suitable for use for classification, but the data indicates that it is likely that the EC50 value for perrhenic acid would be >100 mg/L, and therefore perrhenic acid would not be classified under DSD or CLP regulations.
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.
