Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No readily biodegradable.
Key value for chemical safety assessment
Additional information
The biodegradation in water of the substance was evaluated in a weight of evidence approach by using three studies.
In the first study, the readily bidoegradability of the test item was evaluated by means of a readily biodegradability test performed according to the OECD Guideline 301C. The biodegradability of the test substance was found to be equal to 48, 56 and 52 % by BOD and 67, 80 and 73 % by GC. Aniline was used as reference substance. Under the conditions of the study, the test item was found to be readily biodegradable.
In the second study, the biodegradation of the test item was evaluated by means of a inherently biodegradtion study performed according to the OECD Guideline 302C. After 28 days, the biodegradation of the test item was found to be in the range 79 - 96 % (BOD) and 94 - 95% (GC). In conclusion, under the conditions of the study, the test item was found to be inherently biodegradable.
In the third study, a Sturm test was performed to determine the biodegradation of the test item. The biodegradtion rate of the test item was followed by measuring CO2 evolution. Biodegradation of 53% was found after 9 days, 69 and 95% biodegradation values were found after 12 and 21 days, respectively. Under the condistions of the study, the test item shall be considered as readily biodegradable.
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.
