Additional information
The solubility of the test article in water was investigated according to OECD guideline 105 and EU method A.6.
In the solubility pre-test, the range for the water solubility was stated as 10 – 50 g/L. Therefore, the flask method was used in the main test. In the main test, 250 g/L were used to prepare a saturated solution. Six replicates were prepared. Four vessels (1C (for the sampling point 72 h) and 2 – 4) were set onto the shaking apparatus immediately under dark. After 24 ± 2 hours, flask 1B (for the sampling point 48 h) and after 48 ± 2 hours, flask 1A (for the sampling point 24 h) were set on the shaker and all flasks were shaken for further 24 ± 2 hours at room temperature (20.0 ± 0.5 °C). Then, flasks 1A-C were taken from the shaker, samples were taken, membrane filtrated (0.45 μm, PTFE) and prepared for the analysis via photometer. Because of a difference of less than 15 % in the concentrations on days 2 and 3 and no upward tendency, the test was finished on day 3. The flasks 2 – 4 were sampled on day 3 in the same way. Therefore, the solubility was stated as:
2.37 ± 0.07 g/L at 20.0 ± 0.5 °C = 2.37 ± 0.07 kg/m3 (SI units).
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.
