Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Estimation Programs Interface Suite (EPI suite) was run to predict the biodegradation in water and sediment potential of the test compound Methoxyacetophenone(CAS no 586-37-8). The half life period of Methoxyacetophenonein water is 360 hrs (15 days) therefore it is considered that the substance will qualify as not persistent as the half-life does not exceed the criteria of 60 days. So,it can be confirmed that the substance is readily biodegradable in water medium where as in sediment the half-life is 3240 hrs (135 days). Based on this value, it can be inferred that the substance is persistent in sediment medium and is not readily biodegradable probably due to the anaerobic conditions existing in most sediments.
Key value for chemical safety assessment
- Half-life in freshwater:
- 15 d
- at the temperature of:
- 25 °C
- Half-life in freshwater sediment:
- 135 d
- at the temperature of:
- 25 °C
Additional information
Estimation Programs Interface Suite (EPI suite) was run to predict the biodegradation in water and sediment potential of the test compound Methoxyacetophenone(CAS no 586-37-8). The half life period of Methoxyacetophenonein water is 360 hrs (15 days) therefore it is considered that the substance will qualify as not persistent as the half-life does not exceed the criteria of 40 days. So,it can be confirmed that the substance is readily biodegradable in water medium where as in sediment the half-life is 3240 hrs (135 days). Based on this value, it can be inferred that the substance is persistent in sediment medium and is not readily biodegradable probably due to the anaerobic conditions existing in most sediments.
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.
