Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Endpoint:
- water solubility
- Type of information:
- migrated information: read-across based on grouping of substances (category approach)
- Adequacy of study:
- key study
- Study period:
- 13 to 16 Oct 2009
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'

pH values: Millipore water: 6.8
Column eluate (united): 6.7
Recovery rate
The recovery rate was determined in duplicate (two independent replicates). An average recovery rate of 95% could be determined.
Linearity
Linearity could be shown over the whole calibration range from 0.01 to 5.3 mg/L (related to 40 mL of water, correlation coefficient R = 1.000).
Description of key information
< 1 mg/L
Key value for chemical safety assessment
Additional information
The water solubility of this substance was deduced from the measurement of a similar substance (CAS-No. 28510 -23 -8). Water solubility is a property which decreases with increasing chain length for substances within the same group of chemicals. The chain length of the source substance is C8branched, the chain length of the target substance is C16 -18 and C18 -unsaturated. Therefore the solubility is deduced to be < 1 mg/L.
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.
