Description of key information
The water solubility of (3-Ammonio-4-methoxyphenyl)(2-hydroxyethyl)ammonium sulphate was 81.9 g/L at 20 °C and a pH value of 2.03, measured by flask method (OECD 105). The test item is considered as very soluble (> 10 g/L).
Key value for chemical safety assessment
- Water solubility:
- 81.9 g/L
- at the temperature of:
- 20 °C
Additional information
The water solubility of (3 -Ammonio-4 -methoxyphenyl)(2 -hydroxyethyl) ammonium sulphate was determined following the OECD guideline 105 (flask method) and the GLP.
The test substance was added to double distilled water (15 g/30 mL). The test solutions were pre incubated at 30 ± 0.5 °C with constant stirring at 300 rpm. After 24, 48 and 72 hours flasks were reduced to test temperature (20±0.5°C) with stirring at 100 rpm. Samples were taken 24 hr after transfer to the test temperature and analyzed by HPLC on a reversed-phase column with UV-detection.
The water solubility of test item was 81.9 g/L at 20 °C and a pH value of 2.03, measured by flask method.
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.
