Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

- not biodegradable
- Type of water:
- freshwater
Additional information
Experimental data are available for CAS 147 -14 -8. In a key study conducted similar to OECD guideline 301F (Manometric respirometry test) domestic activated sludge was used as inoculum. A degradation rate of less than 1 % was determined after 28 days (based on O2 consumption, BASF AG, 1988). This result was supported by a second test accomplished according to OECD guideline 301 C. This test was conducted under supervision of the Japanese Ministry of the Environment. The study was performed with a mixture of sewage, soil and natural water as inoculum. The substance was degraded by 0 % based on the O2 consumption after 14 days of incubation (NITE, J-CHECK databank, Japan 1992).
Based on the available experimental data it can be concluded that the substance (CAS 147-14-8) is not readily biodegradable according to OECD criteria.
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.
