Not readily biodegradable (according to OECD criteria)
Key value for chemical safety assessment
Additional information
In a study, performed according to OECD Guideline No. 301 B (1981), 3 and 4 % biodegradation was detected at a test substance concentration of 10 mg/l and 20 mg/l after 28 days, respectively. It is assumed that the test compound was not fully solubilized in water. The results show that the compound is not readily biodegradable.
This result is supported by further data according to OECD TG 301 C, the determination of the COD and predicted data from Catalogic v5.13.1.156.
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.
