Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Study 1 (carried out in 1999) only tested at pH 5. The preliminary analytical method development had indicated the impracticality of testing at pH's 7 and 9 using the established analytical conditions due to chromatographic interference arising from the buffer salts. The conclusion from this test was that the substance was slightly soluble (0.1-100 mg/L) with a result < 0.5 mg/l @ 20 C.
Study 2 (carried out in 2012), preliminary tests were carried out and it was determined that the column elution method be used for pH 4 definitive testing and the shake flask method was used for pH 7 and pH 9 definitive testing. At pH 4 and pH 7 - slightly soluble (0.1 -100mg/L).
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.
