Applicant's summary and conclusion
- Executive summary:
The organic carbon partition coefficient (Koc) for Diazobarbituric acid was predicted using the QSAR calculation of the Estimation Program Interface (EPI) Suite v 4.0. The Koc was estimated to be 15.5 L/kg (logKow method), and 10 L/kg (MCI method). The results relate to the unaffected molecule of the substance as any decomposition (e.g. hydrolysis) of the substance is not taken into account by the program.
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.
