Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance belongs to the category of perylene as indicated by its chemical core structure. Based on this structure and the chemical and biological stability of perylenes under environmental conditions, data from structural analogue perylenes can be used to cover this endpoint required under REACh.
The biodegradability of the analogue substances (CAS 81 -33 -4; EC 479 -300 -2; EC 475 -310 -6) were tested in a guideline studies following OECD 301F. The biodegradation rate was determined by measuring the O2 consumption of domestic activated sludge. At test termination after 28 days a degradation rate of <10 % was determined, respectively [BASF AG 1999, BASF 2006].
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.
