Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The UVVis absorption properties and the solubility of the test item in water are very low. An experimental determination of the dissociation constant was therefore not possible. According to the guidance on information requirements and chemical safety assessment 2008 (Chapter R.7a) and to the OECD guideline 112, the described method is only suitable for substances that have considerably different UVVis absorbance in the ionised and unionised forms or for water soluble substances.
Key value for chemical safety assessment
Additional information
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.
