Description of key information
The half-live of the test item is at least 1444 days.
The test item is regarded as not biodegradable.
Additional information
Under sterile conditions at 25 °C in the dark, the test item is very stable in buffered aqueous solutions at pH levels of 5, 7 and 9. The observed half-lives of the test item ranged from 1444 to 4620 days. In addition to the parent compound, one other substance was observed during the study. Further investigations using HPLC co-chromatography proved the substance was not a true hydrolytic degradate but an impurity associated with the test chemical. The parent compound was confirmed chromatographically by RP-HPLC and LC/MS.
The stability of the test item was determined in an aerobic test system with sediment from a natural stream in US. The optical density measured at 395 nm showed no significant decline after the test duration of 2.5 months. The test item is regarded as not 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.
