Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The test substance is not readily biodegradable according to OECD criteria.
Key value for chemical safety assessment
Additional information
A GLP guideline study according to OECD 301F has been conducted (RCC UMWELTCHEMIE AG 1995a). Activated bacterial sludge from a domestic waste water plant has been used and the biodegradation has been investigated by measuring the biological oxygen demand (BOD). After 28 d no biodegradation has been observed for the test substance. Therefore, the test substance is not readily biodegradable according to OECD criteria.
Aniline was used as a control and was degraded by 72.9 % and 69.9 % after 14 days of exposure. At the end of the test, degradation rates of 82.9 % and 77.4 % were measured. No inhibitory effects were observed in the toxicity controls.
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.
