Any other information on results incl. tables
A saturated solution was used.
Solubility is < 0.1 mg/L according GLP test RCC project 638381. No exact concentration was determinable.
Preparation of the test solution:
An aqueous solution of the test article was prepared by weighing 2.40 g of test article and adding 100 ml of bidistilled water. The mixture was stirred for 17 hours and thereafter filtrated to remove undissolved material. Prior to the measurement, 9 parts of the saturated solution of the test article was diluted with one part of bidistilled water (V/V).
Applicant's summary and conclusion
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.
