Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Aqueous solutions of the test item were prepared in different buffer solutions pH 4, 7 and 9 to investigate its stability according to OECD guideline 111. The analytical behavior of the test item was investigated first in order to obtain an analytical method for the analysis of the sample solutions by HPLC/UV-detection. For the freshly prepared solutions the validity criteria for the used concentration range have been met using calibration curves/linear regression.However, in course of these measurements alterations of the HPLC signal shapes were observed after 1 day respectively.
This effect was attributed to chemical interaction of the test item with the different buffer solution salts. Therefore, the study is regarded as technically not feasible.
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.
