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. The ADONA toxicity tests are functionally tests of the combined toxicity of ammonium and DONA anion. Aquatic toxicity testing with DONA as a starting material would be conducted at near-neutral pH. Given a pKa of ca. 2, the organisms would also be exposed to DONA anion if these studies were conducted. Because no toxicity was observed of ADONA, there is no confounding of DONA toxicity with ammonium toxicity, and the ADONA results 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.
