Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Risk Characterization Ratio (i. e. PEC/PNEC ratio) sediment compartment < 1
Key value for chemical safety assessment
Additional information
No experimental data evaluating the toxicity of 4,4´-(9H-fluoren-9-ylidene)bis(2-chloroaniline) (CAS No. 107934-68-9) to sediment organisms are available. According to Annex IX, Column 2, 9.5.1, of Regulation 1907/2006, long-term toxicity testing shall be proposed by the registrant if the results of the chemical safety assessment indicate the need to investigate further the effects of the substance and/or relevant degradation products on sediment organisms. The environmental exposure assessment performed for this substance (see CSR attached to IUCLID section 13) shows that indeed the Risk Characterization Ratio (i. e. PEC/PNEC ratio) in the sediment compartment is < 1 and therefore, under the current exposure conditions, 4,4´-(9H-fluoren-9-ylidene) bis(2-chloroaniline) (CAS No. 107934-68-9) does not pose a risk to sediment organisms and further testing is not deemed necessary according to Regulation (EC) No. 1907/2006, Annex XI, section 3.
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.
