Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Test results for ADONA, the ammonium salt, are also reported for DONA free acid. ADONA exists in dissociated form, as ammonium and DONA anion, in aqueous solution. Given a pKa ca. 2, DONA free acid will also exist as the anion under environmentally relevant conditions. Biodegradation testing of ADONA was conducted using an OECD guideline 301B. Since this test measures evolution of carbon dioxide, it would detect potential biotransformation of DONA anion and cannot detect biotransformation of ammonium. Therefore, the ADONA biodegradation result is directly applicable to DONA. In the BCF and Koc tests, DONA was the only analyte monitored. Both tests were conducted at pH ca. 7, which would maintain DONA in anionic form. Because these two tests, if done using DONA as the starting material, would also be conducted at near-neutral pH, results of the ADONA tests are directly applicable to DONA.
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.
