- Details on results:
- A half-life of approx. 13 days was determined under environmentally relevant conditions (pH: 7, T: 25 degrees C). It is not assumed that this influenced the result of the water toxicity test. The report concludes that a pseudo reaction of the first order is involved here.
Method: a HPLC analysis with methanol/water as a mobile phase and UV detection was performed.
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.
